-/**
- * Bluetooth Bassclient StateMachine. There is one instance per remote device.
- *  - "Disconnected" and "Connected" are steady states.
- *  - "Connecting" and "Disconnecting" are transient states until the
- *     connection / disconnection is completed.
- *  - "ConnectedProcessing" is an intermediate state to ensure, there is only
- *    one Gatt transaction from the profile at any point of time
- *
- *
- *                        (Disconnected)
- *                           |       ^
- *                   CONNECT |       | DISCONNECTED
- *                           V       |
- *                 (Connecting)<--->(Disconnecting)
- *                           |       ^
- *                 CONNECTED |       | DISCONNECT
- *                           V       |

- *                          (ConnectedProcessing)
- * NOTES:
- *  - If state machine is in "Connecting" state and the remote device sends
- *    DISCONNECT request, the state machine transitions to "Disconnecting" state.
- *  - Similarly, if the state machine is in "Disconnecting" state and the remote device
- *    sends CONNECT request, the state machine transitions to "Connecting" state.
- *  - Whenever there is any Gatt Write/read, State machine will moved "ConnectedProcessing" and
- *    all other requests (add, update, remove source) operations will be deferred in
- *    "ConnectedProcessing" state
- *  - Once the gatt transaction is done (or after a specified timeout of no response),
- *    State machine will move back to "Connected" and try to process the deferred requests
- *    as needed
- *
- *                    DISCONNECT

-# Blueberry Android server
-
-The Blueberry Android server exposes the [Blueberry test interfaces](
-go/blueberry-doc) over gRPC implemented on top of the Android Bluetooth SDK.
-
-## Getting started
-
-Using Blueberry Android server requires to:
-
-* Build AOSP for your DUT, which can be either a physical device or an Android
-  Virtual Device (AVD).
-* [Only for virtual tests] Build Rootcanal, the Android
-  virtual Bluetooth Controller.
-* Setup your test environment.
-* Build, install, and run Blueberry server.
-* Run your tests.
-
-### 1. Build and run AOSP code
-
-Refer to the AOSP documentation to [initialize and sync](
-https://g3doc.corp.google.com/company/teams/android/developing/init-sync.md)
-AOSP code, and [build](
-https://g3doc.corp.google.com/company/teams/android/developing/build-flash.md)
-it for your DUT (`aosp_cf_x86_64_phone-userdebug` for the emulator).
-
-**If your DUT is a physical device**, flash the built image on it. You may
-need to use [Remote Device Proxy](
-https://g3doc.corp.google.com/company/teams/android/wfh/adb/remote_device_proxy.md)
-if you are using a remote instance to build. If you are also using `adb` on
-your local machine, you may need to force kill the local `adb` server (`adb
-kill-server` before using Remote Device Proxy.
-
-**If your DUT is a Cuttlefish virtual device**, then proceed with the following steps:
-
-* Connect to your [Chrome Remote Desktop](
-  https://remotedesktop.corp.google.com/access/).
-* Create a local Cuttlefish instance using your locally built image with the command
-  `acloud create --local-instance --local-image` (see [documentation](
-  go/acloud-manual#local-instance-using-a-locally-built-image))
-
-### 2. Build Rootcanal [only for virtual tests on a physical device]
-
-Rootcanal is a virtual Bluetooth Controller that allows emulating Bluetooth
-communications. It is used by default within Cuttlefish when running it using the [acloud](go/acloud) command (and thus this step is not
-needed) and is required for all virtual tests. However, it does not come
-preinstalled on a build for a physical device.
-
-Proceed with the [following instructions](
-https://docs.google.com/document/d/1-qoK1HtdOKK6sTIKAToFf7nu9ybxs8FQWU09idZijyc/edit#heading=h.x9snb54sjlu9)
-to build and install Rootcanal on your DUT.
-
-### 3. Setup your test environment
-
-Each time when starting a new ADB server to communicate with your DUT, proceed
-with the following steps to setup the test environment:
-
-* If running virtual tests (such as PTS-bot) on a physical device:
-  * Run Rootcanal:
-    `adb root` then
-    `adb shell ./vendor/bin/hw/android.hardware.bluetooth@1.1-service.sim &`
-  * Forward Rootcanal port through ADB:
-    `adb forward tcp:<rootcanal-port> tcp:<rootcanal-port>`.
-    Rootcanal port number may differ depending on its configuration. It is
-    7200 for the AVD, and generally 6211 for physical devices.
-* Forward Blueberry Android server port through ADB:
-  `adb forward tcp:8999 tcp:8999`.
-
-The above steps can be done by executing the `setup.sh` helper script (the
-`-rootcanal` option must be used for virtual tests on a physical device).
-
-Finally, you must also make sure that the machine on which tests are executed
-can access the ports of the Blueberry Android server, Rootcanal (if required),
-and ADB (if required).
-
-You can also check the usage examples provided below.
-
-### 4. Build, install, and run Blueberry Android server
-
-* `m BlueberryServer`
-* `adb install -r -g out/target/product/<device>/testcases/Blueberry/arm64/Blueberry.apk`
-
-* Start the instrumented app:
-* `adb shell am instrument -w -e Debug false com.android.blueberry/.Server`
-
-### 5. Run your tests
-
-You should now be fully set up to run your tests!
-
-### Usage examples
-
-Here are some usage examples:
-
-* **DUT**: physical
-  **Test type**: virtual
-  **Test executer**: remote instance (for instance a Cloudtop) accessed via SSH
-  **Blueberry Android server repository location**: local machine (typically
-  using Android Studio)
-
-  * On your local machine: `./setup.sh --rootcanal`.
-  * On your local machine: build and install the app on your DUT.
-  * Log on your remote instance, and forward Rootcanal port (6211, may change
-    depending on your build) and Blueberry Android server (8999) port:
-    `ssh -R 6211:localhost:6211 -R 8999:localhost:8999 <remote-instance>`.
-    Optionnally, you can also share ADB port to your remote instance (if
-    needed) by adding `-R 5037:localhost:5037` to the command.
-  * On your remote instance: execute your tests.
-
-* **DUT**: virtual (running in remote instance)
-  **Test type**: virtual
-  **Test executer**: remote instance
-  **Blueberry Android server repository location**: remote instance
-
-  On your remote instance:
-  * `./setup.sh`.
-  * Build and install the app on the AVD.
-  * Execute your tests.

+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.
+
+      To apply the Apache License to your work, attach the following
+      boilerplate notice, with the fields enclosed by brackets "[]"

+# Pandora Android server
+
+The Pandora Android server exposes the [Pandora test interfaces](
+go/pandora-doc) over gRPC implemented on top of the Android Bluetooth SDK.
+
+## Getting started
+
+Using Pandora Android server requires to:
+
+* Build AOSP for your DUT, which can be either a physical device or an Android
+  Virtual Device (AVD).
+* [Only for virtual tests] Build Rootcanal, the Android
+  virtual Bluetooth Controller.
+* Setup your test environment.
+* Build, install, and run Pandora server.
+* Run your tests.
+
+### 1. Build and run AOSP code
+
+Refer to the AOSP documentation to [initialize and sync](
+https://g3doc.corp.google.com/company/teams/android/developing/init-sync.md)
+AOSP code, and [build](
+https://g3doc.corp.google.com/company/teams/android/developing/build-flash.md)
+it for your DUT (`aosp_cf_x86_64_phone-userdebug` for the emulator).
+
+**If your DUT is a physical device**, flash the built image on it. You may
+need to use [Remote Device Proxy](
+https://g3doc.corp.google.com/company/teams/android/wfh/adb/remote_device_proxy.md)
+if you are using a remote instance to build. If you are also using `adb` on
+your local machine, you may need to force kill the local `adb` server (`adb
+kill-server` before using Remote Device Proxy.
+
+**If your DUT is a Cuttlefish virtual device**, then proceed with the following steps:
+
+* Connect to your [Chrome Remote Desktop](
+  https://remotedesktop.corp.google.com/access/).
+* Create a local Cuttlefish instance using your locally built image with the command
+  `acloud create --local-instance --local-image` (see [documentation](
+  go/acloud-manual#local-instance-using-a-locally-built-image))
+
+### 2. Build Rootcanal [only for virtual tests on a physical device]
+
+Rootcanal is a virtual Bluetooth Controller that allows emulating Bluetooth
+communications. It is used by default within Cuttlefish when running it using the [acloud](go/acloud) command (and thus this step is not
+needed) and is required for all virtual tests. However, it does not come
+preinstalled on a build for a physical device.
+
+Proceed with the [following instructions](
+https://docs.google.com/document/d/1-qoK1HtdOKK6sTIKAToFf7nu9ybxs8FQWU09idZijyc/edit#heading=h.x9snb54sjlu9)
+to build and install Rootcanal on your DUT.
+
+### 3. Setup your test environment
+
+Each time when starting a new ADB server to communicate with your DUT, proceed
+with the following steps to setup the test environment:
+
+* If running virtual tests (such as PTS-bot) on a physical device:
+  * Run Rootcanal:
+    `adb root` then
+    `adb shell ./vendor/bin/hw/android.hardware.bluetooth@1.1-service.sim &`
+  * Forward Rootcanal port through ADB:
+    `adb forward tcp:<rootcanal-port> tcp:<rootcanal-port>`.
+    Rootcanal port number may differ depending on its configuration. It is
+    7200 for the AVD, and generally 6211 for physical devices.
+* Forward Pandora Android server port through ADB:
+  `adb forward tcp:8999 tcp:8999`.
+
+The above steps can be done by executing the `setup.sh` helper script (the
+`-rootcanal` option must be used for virtual tests on a physical device).
+
+Finally, you must also make sure that the machine on which tests are executed
+can access the ports of the Pandora Android server, Rootcanal (if required),
+and ADB (if required).
+
+You can also check the usage examples provided below.
+
+### 4. Build, install, and run Pandora Android server
+
+* `m PandoraServer`
+* `adb install -r -g out/target/product/<device>/testcases/Pandora/arm64/Pandora.apk`
+
+* Start the instrumented app:
+* `adb shell am instrument -w -e Debug false com.android.pandora/.Server`
+
+### 5. Run your tests
+
+You should now be fully set up to run your tests!
+
+### Usage examples
+
+Here are some usage examples:
+
+* **DUT**: physical
+  **Test type**: virtual
+  **Test executer**: remote instance (for instance a Cloudtop) accessed via SSH
+  **Pandora Android server repository location**: local machine (typically
+  using Android Studio)
+
+  * On your local machine: `./setup.sh --rootcanal`.
+  * On your local machine: build and install the app on your DUT.
+  * Log on your remote instance, and forward Rootcanal port (6211, may change
+    depending on your build) and Pandora Android server (8999) port:
+    `ssh -R 6211:localhost:6211 -R 8999:localhost:8999 <remote-instance>`.
+    Optionnally, you can also share ADB port to your remote instance (if
+    needed) by adding `-R 5037:localhost:5037` to the command.
+  * On your remote instance: execute your tests.
+
+* **DUT**: virtual (running in remote instance)
+  **Test type**: virtual
+  **Test executer**: remote instance
+  **Pandora Android server repository location**: remote instance
+
+  On your remote instance:
+  * `./setup.sh`.
+  * Build and install the app on the AVD.
+  * Execute your tests.

+ *
+ * <p>HF/CT side applications on can use {@link BluetoothDevice#requestAudioPolicyAsSink}
+ * API to set and send a {@link BluetoothSinkAudioPolicy} object containing the
+ * preference/policy values. This object will be stored in the memory of HF/CT

-[WHITESPACE](#Whitespace) and [COMMENT](#Comment) are implicitly inserted between every item
-and repetitions in syntactical rules (snake_case).
-
-```
-file: endianess declaration*
-```
-behaves like:
-```
-file: (WHITESPACE | COMMENT)* endianess (WHITESPACE | COMMENT)* (declaration | WHITESPACE | COMMENT)*
-```
-
-## File
-
-> file:\
-> &nbsp;&nbsp; endianess [declaration](#declarations)*
->
-> endianess:\
-> &nbsp;&nbsp; `little_endian_packets` | `big_endian_packets`
-
-The structure of a `.pdl`file is:
-1. A declaration of the protocol endianess: `little_endian_packets` or `big_endian_packets`. Followed by
-2. Declarations describing the structure of the protocol.
-
-```
-// The protocol is little endian
-little_endian_packets
-
-// Brew a coffee
-packet Brew {
-  pot: 8, // Output Pot: 8bit, 0-255
-  additions: CoffeeAddition[2] // Coffee Additions: array of 2 CoffeeAddition
-}
-```
-
-## Identifiers
-
-- Identifiers can denote a field; an enumeration tag; or a declared type.
-
-- Field identifiers declared in a [packet](#packet) (resp. [struct](#struct)) belong to the _scope_ that extends
-  to the packet (resp. struct), and all derived packets (resp. structs).
-
-- Field identifiers declared in a [group](#group) belong to the _scope_ that
-  extends to the packets declaring a [group field](#group_field) for this group.
-
-- Two fields may not be declared with the same identifier in any packet scope.
-
-- Two types may not be declared width the same identifier.
-
-## Declarations
-
-> declaration: {#declaration}\
-> &nbsp;&nbsp; [enum_declaration](#enum) |\
-> &nbsp;&nbsp; [packet_declaration](#packet) |\
-> &nbsp;&nbsp; [struct_declaration](#struct) |\
-> &nbsp;&nbsp; [group_declaration](#group) |\
-> &nbsp;&nbsp; [checksum_declaration](#checksum) |\
-> &nbsp;&nbsp; [custom_field_declaration](#custom-field) |\
-> &nbsp;&nbsp; [test_declaration](#test)
-
-A *declaration* defines a type inside a `.pdl` file. A declaration can reference
-another declaration appearing later in the file.
-
-A declaration is either:
-- an [Enum](#enum) declaration
-- a [Packet](#packet) declaration
-- a [Struct](#struct) declaration
-- a [Group](#group) declaration
-- a [Checksum](#checksum) declaration
-- a [Custom Field](#custom-field) declaration
-- a [Test](#test) declaration
-
-### Enum
-
-> enum_declaration:\
-> &nbsp;&nbsp; `enum` [IDENTIFIER](#identifier) `:` [INTEGER](#integer) `{`\
-> &nbsp;&nbsp;&nbsp;&nbsp; enum_tag_list\
-> &nbsp;&nbsp; `}`
->
-> enum_tag_list:\
-> &nbsp;&nbsp; enum_tag (`,` enum_tag)* `,`?
->
-> enum_tag:\
-> &nbsp;&nbsp; [IDENTIFIER](#identifier) `=` [INTEGER](#integer)
-
-An *enumeration* or for short *enum*, is a declaration of a set of named [integer](#integer) constants.
-
-The [integer](#integer) following the name specifies the bit size of the values.
-
-```
-enum CoffeeAddition: 3 {
-  Empty = 0,
-  Cream = 1,
-  Vanilla = 2,
-  Chocolate = 3,
-  Whisky = 4,
-  Rum = 5,
-  Kahlua = 6,
-  Aquavit = 7
-}
-```
-
-### Packet
-
-> packet_declaration:\
-> &nbsp;&nbsp; `packet` [IDENTIFIER](#identifier)\
-> &nbsp;&nbsp;&nbsp;&nbsp; (`:` [IDENTIFIER](#identifier)\
-> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (`(` [constraint_list](#constraints) `)`)?\
-> &nbsp;&nbsp;&nbsp;&nbsp; )?\
-> &nbsp;&nbsp; `{`\
-> &nbsp;&nbsp;&nbsp;&nbsp; [field_list](#fields)?\
-> &nbsp;&nbsp; `}`
-
-A *packet* is a declaration of a sequence of [fields](#fields).
-
-A *packet* can optionally inherit from another *packet* declaration. In this case the packet
-inherits the parent's fields and the child's fields replace the
-[*\_payload\_*](#fields-payload) or [*\_body\_*](#fields-body) field of the parent.
-
-When inheriting, you can use constraints to set values on parent fields.
-See [constraints](#constraints) for more details.
-
-```
-packet Error {
-  code: 32,
-  _payload_
-}
-
-packet ImATeapot: Error(code = 418) {
-  brand_id: 8
-}
-```
-
-### Struct
-
-> struct_declaration:\
-> &nbsp;&nbsp; `struct` [IDENTIFIER](#identifier)\
-> &nbsp;&nbsp;&nbsp;&nbsp; (`:` [IDENTIFIER](#identifier)\
-> &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; (`(` [constraint_list](#constraints) `)`)?\
-> &nbsp;&nbsp;&nbsp;&nbsp; )?\
-> &nbsp;&nbsp; `{`\
-> &nbsp;&nbsp;&nbsp;&nbsp; [field_list](#fields)?\
-> &nbsp;&nbsp; `}`
-
-A *struct* follows the same rules as a [*packet*](#packet) with the following differences:
-- It inherits from a *struct* declaration instead of *packet* declaration.
-- A [typedef](#fields-typedef) field can reference a *struct*.
-
-### Group
-
-> group_declaration:\
-> &nbsp;&nbsp; `group` [IDENTIFIER](#identifier) `{`\
-> &nbsp;&nbsp;&nbsp;&nbsp; [field_list](#fields)\
-> &nbsp;&nbsp; `}`
-
-A *group* is a sequence of [fields](#fields) that expand in a
-[packet](#packet) or [struct](#struct) when used.
-
-See also the [Group field](#fields-group).
-
-```
-group Paged {
-  offset: 8,
-  limit: 8
-}
-
-packet AskBrewHistory {
-  pot: 8, // Coffee Pot
-  Paged
-}
-```
-behaves like:
-```
-packet AskBrewHistory {
-  pot: 8, // Coffee Pot
-  offset: 8,
-  limit: 8
-}
-```
-
-### Checksum
-
-> checksum_declaration:\
-> &nbsp;&nbsp; `checksum` [IDENTIFIER](#identifier) `:` [INTEGER](#integer) [STRING](#string)
-
-A *checksum* is a native type (not implemented in PDL). See your generator documentation
-for more information on how to use it.
-
-The [integer](#integer) following the name specify the bit size of the checksum value.
-The [string](#string) following the size is a value defined by the generator implementation.
-
-```
-checksum CRC16: 16 "crc16"
-```
-
-### Custom Field
-
-> custom_field_declaration:\
-> &nbsp;&nbsp; `custom_field` [IDENTIFIER](#identifier) (`:` [INTEGER](#integer))? [STRING](#string)
-
-A *custom field* is a native type (not implemented in PDL). See your generator documentation for more
-information on how to use it.
-
-If present, the [integer](#integer) following the name specify the bit size of the value.
-The [string](#string) following the size is a value defined by the generator implementation.
-
-```
-custom_field URL "url"
-```
-
-### Test
-
-> test_declaration:\
-> &nbsp;&nbsp; `test` [IDENTIFIER](#identifier) `{`\
-> &nbsp;&nbsp;&nbsp;&nbsp; test_case_list\
-> &nbsp;&nbsp; `}`
->
-> test_case_list:\
-> &nbsp;&nbsp; test_case (`,` test_case)* `,`?
->
-> test_case:\
-> &nbsp;&nbsp; [STRING](#string)
-
-A *test* declares a set of valid octet representations of a packet identified by its name.
-The generator implementation defines how to use the test data.
-
-A test passes if the packet parser accepts the input; if you want to test
-the values returned for each field, you may specify a derived packet with field values enforced using
-constraints.
-
-```
-packet Brew {
-  pot: 8,
-  addition: CoffeeAddition
-}
-
-test Brew {
-  "\x00\x00",
-  "\x00\x04"
-}
-
-// Fully Constrained Packet
-packet IrishCoffeeBrew: Brew(pot = 0, additions_list = Whisky) {}
-
-test IrishCoffeeBrew {
-  "\x00\x04"
-}
-```
-
-## Constraints
-
-> constraint:\
-> &nbsp;&nbsp; [IDENTIFIER](#identifier) `=` [IDENTIFIER](#identifier) | [INTEGER](#integer)
->
-> constraint_list:\
-> &nbsp;&nbsp; constraint (`,` constraint)* `,`?
-
-A *constraint* defines the value of a parent field.
-The value can either be an [enum](#enum) tag or an [integer](#integer).
-
-```
-group Additionable {
-  addition: CoffeAddition
-}
-
-packet IrishCoffeeBrew {
-  pot: 8,
-  Additionable {
-    addition = Whisky
-  }
-}
-
-packet Pot0IrishCoffeeBrew: IrishCoffeeBrew(pot = 0) {}
-```
-

-  addition: CoffeeAddition
-}
-```
-
-### Array {#fields-array}
-
-> array_field:\
-> &nbsp;&nbsp; [IDENTIFIER](#identifier) `:` [INTEGER](#integer) | [IDENTIFIER](#identifier) `[`\
-> &nbsp;&nbsp;&nbsp;&nbsp; [SIZE_MODIFIER](#size-modifier) | [INTEGER](#integer)\
-> &nbsp;&nbsp; `]`
-
-An *array* field defines a sequence of `N` elements of type `T`.
-
-`N` can be:
-- An [integer](#integer) value.
-- A [size modifier](#size-modifier).
-- Unspecified: In this case the array is dynamically sized using a
-[*\_size\_*](#fields-size) or a [*\_count\_*](#fields-count).
-
-`T` can be:
-- An [integer](#integer) denoting the bit size of one element.
-- An [identifier](#identifier) referencing an [enum](#enum), a [struct](#struct)
-or a [custom field](#custom-field) type.
-
-```
-packet Brew {
-   pots: 8[2],
-   additions: CoffeeAddition[2],
-   extra_additions: CoffeeAddition[],
-}
-```
-
-### Group {#fields-group}
-
-> group_field:\
-> &nbsp;&nbsp; [IDENTIFIER](#identifier) (`{` [constraint_list](#constraints) `}`)?
-
-A *group* field inlines all the fields defined in the referenced group.
-
-If a [constraint list](#constraints) constrains a [scalar](#fields-scalar) field
-or [typedef](#fields-typedef) field with an [enum](#enum) type, the field will
-become a [fixed](#fields-fixed) field.
-The [fixed](#fields-fixed) field inherits the type or size of the original field and the
-value from the constraint list.
-
-See [Group Declaration](#group) for more information.
-
-### Size {#fields-size}
-
-> size_field:\
-> &nbsp;&nbsp; `_size_` `(` [IDENTIFIER](#identifier) | `_payload_` | `_body_` `)` `:` [INTEGER](#integer)
-
-A *\_size\_* field is a [scalar](#fields-scalar) field with as value the size in octet of the designated
-[array](#fields-array), [*\_payload\_*](#fields-payload) or [*\_body\_*](#fields-body).
-
-```
-packet Parent {
-  _size_(_payload_): 2,
-  _payload_
-}
-
-packet Brew {
-  pot: 8,
-  _size_(additions): 8,
-  additions: CoffeeAddition[]
-}
-```
-
-### Count {#fields-count}

-> count_field:\
-> &nbsp;&nbsp; `_count_` `(` [IDENTIFIER](#identifier) `)` `:` [INTEGER](#integer)
-
-A *\_count\_* field is a [*scalar*](#fields-scalar) field with as value the number of elements of the designated
-[array](#fields-array).
-
-```
-packet Brew {
-  pot: 8,
-  _count_(additions): 8,
-  additions: CoffeeAddition[]
-}
-```
-
-### Payload {#fields-payload}
-
-> payload_field:\
-> &nbsp;&nbsp; `_payload_` (`:` `[` [SIZE_MODIFIER](#size-modifier) `]` )?
-
-A *\_payload\_* field is a dynamically sized array of octets.
-
-It declares where to parse the definition of a child [packet](#packet) or [struct](#struct).
-
-A [*\_size\_*](#fields-size) or a [*\_count\_*](#fields-count) field referencing
-the payload induce its size.
-
-If used, a [size modifier](#size-modifier) can alter the octet size.
-
-### Body {#fields-body}
-
-> body_field:\
-> &nbsp;&nbsp; `_body_`
-
-A *\_body\_* field is like a [*\_payload\_*](#fields-payload) field with the following differences:
-- The body field is private to the packet definition, it's accessible only when inheriting.
-- The body does not accept a size modifier.
-
-### Fixed {#fields-fixed}
-
-> fixed_field:\
-> &nbsp;&nbsp; `_fixed_` `=` \
-> &nbsp;&nbsp;&nbsp;&nbsp; ( [INTEGER](#integer) `:` [INTEGER](#integer) ) |\
-> &nbsp;&nbsp;&nbsp;&nbsp; ( [IDENTIFIER](#identifier) `:` [IDENTIFIER](#identifier) )
-
-A *\_fixed\_* field defines a constant with a known bit size.
-The constant can be either:
-- An [integer](#integer) value
-- An [enum](#enum) tag
-
-```
-packet Teapot {
-  _fixed_ = 42: 8,
-  _fixed_ = Empty: CoffeeAddition
-}
-```
-
-### Checksum {#fields-checksum}
-
-> checksum_field:\
-> &nbsp;&nbsp; `_checksum_start_` `(` [IDENTIFIER](#identifier) `)`
-
-A *\_checksum_start\_* field is a zero sized field that acts as a marker for the beginning of
-the fields covered by a checksum.
-
-The *\_checksum_start\_* references a [typedef](#fields-typedef) field
-with a [checksum](#checksum) type that stores the checksum value and selects the algorithm
-for the checksum.
-
-```
-checksum CRC16: 16 "crc16"
-
-packet CRCedBrew {
-  crc: CRC16,
-  _checksum_start_(crc),
-  pot: 8,
-}
-```
-
-### Padding {#fields-padding}
-
-> padding_field:\
-> &nbsp;&nbsp; `_padding_` `[` [INTEGER](#integer) `]`
-
-A *\_padding\_* field adds a number of **octet** of padding.
-
-```
-packet Padded {
-  _padding_[1] // 1 octet/8bit of padding
-}
-```
-
-### Reserved {#fields-reserved}
-
-> reserved_field:\
-> &nbsp;&nbsp; `_reserved_` `:` [INTEGER](#integer)
-
-A *\_reserved\_* field adds reserved bits.

+# Packet Description Language (PDL)
+
+PDL is a domain specific language for writing the definition of binary protocol
+packets. Parsing and validating packets from raw bytes is tedious and error
+prone in any language. PDL generates memory safe and tailored backends for
+mulitple target languages:
+
+    - Rust
+    - C++
+    - Python
+
+## How to use PDL
+
+1. Write the protocol definition
+1. `cargo run my-protocol.pdl --output-format rust > my-protocol.rs`
+
+Language specific instructions are provided in another section.
+
+## Supported Features
+
+[Full reference documentation](#doc/reference.md)
+- Scalar values
+- Enumerators
+- Arrays
+- Nested packets
+- Conditional packet derivation
+- Custom field definitions

+## File

+> file:\
+> &nbsp;&nbsp; endianess [declaration](#declarations)*
+>
+> endianess:\
+> &nbsp;&nbsp; `little_endian_packets` | `big_endian_packets`
+
+The structure of a `.pdl`file is:
+1. A declaration of the protocol endianess: `little_endian_packets` or `big_endian_packets`. Followed by
+2. Declarations describing the structure of the protocol.
+
+```
+// The protocol is little endian
+little_endian_packets
+
+// Brew a coffee
+packet Brew {
+  pot: 8, // Output Pot: 8bit, 0-255
+  additions: CoffeeAddition[2] // Coffee Additions: array of 2 CoffeeAddition
+}
+```
+
+The endianess affects how fields of fractional byte sizes (hence named
+bit-fields) are parsed or serialized. Such fields are grouped together to the
+next byte boundary, least significant bit first, and then byte-swapped to the
+required endianess before being written to memory, or after being read from
+memory.
+
+```
+packet Coffee {
+  a: 1,
+  b: 15,
+  c: 3,
+  d: 5,
+}
+
+// The first two field are laid out as a single
+// integer of 16-bits
+//     MSB                                   LSB
+//     16                  8                 0

+//     +---------------------------------------+
+//
+// The file endianness is applied to this integer
+// to obtain the byte layout of the packet fields.
+//

+
+Fields which qualify as bit-fields are:
+- [Scalar](#fields-scalar) fields
+- [Size](#fields-size) fields
+- [Count](#fields-count) fields
+- [Fixed](#fields-fixed) fields
+- [Reserved](#fields-reserved) fields
+- [Typedef](#fields-typedef) fields, when the field type is an
+  [Enum](#enum)
+
+Fields that do not qualify as bit-fields _must_ start and end on a byte boundary.
+
+## Identifiers
+
+- Identifiers can denote a field; an enumeration tag; or a declared type.
+
+- Field identifiers declared in a [packet](#packet) (resp. [struct](#struct)) belong to the _scope_ that extends
+  to the packet (resp. struct), and all derived packets (resp. structs).
+
+- Field identifiers declared in a [group](#group) belong to the _scope_ that
+  extends to the packets declaring a [group field](#group_field) for this group.
+
+- Two fields may not be declared with the same identifier in any packet scope.
+
+- Two types may not be declared width the same identifier.
+

+> &nbsp;&nbsp; [checksum_declaration](#checksum) |\
+> &nbsp;&nbsp; [custom_field_declaration](#custom-field) |\
+> &nbsp;&nbsp; [test_declaration](#test)
+
+A *declaration* defines a type inside a `.pdl` file. A declaration can reference
+another declaration appearing later in the file.
+
+A declaration is either:
+- an [Enum](#enum) declaration
+- a [Packet](#packet) declaration
+- a [Struct](#struct) declaration
+- a [Group](#group) declaration
+- a [Checksum](#checksum) declaration
+- a [Custom Field](#custom-field) declaration
+- a [Test](#test) declaration

+> &nbsp;&nbsp; [IDENTIFIER](#identifier) `=` [INTEGER](#integer)
+
+An *enumeration* or for short *enum*, is a declaration of a set of named [integer](#integer) constants
+or named [integer](#integer) ranges. [integer](#integer) ranges are inclusive in both ends.
+[integer](#integer) value within a range *must* be unique. [integer](#integer) ranges
+*must not* overlap.
+
+The [integer](#integer) following the name specifies the bit size of the values.
+
+```
+enum CoffeeAddition: 5 {
+  Empty = 0,
+
+  NonAlcoholic = 1..9 {
+    Cream = 1,
+    Vanilla = 2,
+    Chocolate = 3,
+  },
+
+  Alcoholic = 10..19 {
+    Whisky = 10,
+    Rum = 11,
+    Kahlua = 12,
+    Aquavit = 13,
+  },
+
+  Custom = 20..29,
+}
+```
+
+### Packet

+> &nbsp;&nbsp;&nbsp;&nbsp; )?\
+> &nbsp;&nbsp; `{`\
+> &nbsp;&nbsp;&nbsp;&nbsp; [field_list](#fields)?\
+> &nbsp;&nbsp; `}`
+
+A *packet* is a declaration of a sequence of [fields](#fields). While packets
+can contain bit-fields, the size of the whole packet must be a multiple of 8
+bits.
+
+A *packet* can optionally inherit from another *packet* declaration. In this case the packet
+inherits the parent's fields and the child's fields replace the
+[*\_payload\_*](#fields-payload) or [*\_body\_*](#fields-body) field of the parent.
+
+When inheriting, you can use constraints to set values on parent fields.
+See [constraints](#constraints) for more details.
+
+```
+packet Error {
+  code: 32,
+  _payload_
+}
+
+packet ImATeapot: Error(code = 418) {
+  brand_id: 8
+}
+```

+> &nbsp;&nbsp;&nbsp;&nbsp; )?\
+> &nbsp;&nbsp; `{`\
+> &nbsp;&nbsp;&nbsp;&nbsp; [field_list](#fields)?\
+> &nbsp;&nbsp; `}`
+
+A *struct* follows the same rules as a [*packet*](#packet) with the following differences:
+- It inherits from a *struct* declaration instead of *packet* declaration.
+- A [typedef](#fields-typedef) field can reference a *struct*.
+
+### Group
+
+> group_declaration:\
+> &nbsp;&nbsp; `group` [IDENTIFIER](#identifier) `{`\
+> &nbsp;&nbsp;&nbsp;&nbsp; [field_list](#fields)\
+> &nbsp;&nbsp; `}`
+
+A *group* is a sequence of [fields](#fields) that expand in a
+[packet](#packet) or [struct](#struct) when used.
+
+See also the [Group field](#fields-group).
+
+```
+group Paged {
+  offset: 8,
+  limit: 8
+}
+
+packet AskBrewHistory {
+  pot: 8, // Coffee Pot
+  Paged
+}
+```
+behaves like:
+```

+  pot: 8, // Coffee Pot
+  offset: 8,
+  limit: 8
+}

+### Checksum
+
+> checksum_declaration:\
+> &nbsp;&nbsp; `checksum` [IDENTIFIER](#identifier) `:` [INTEGER](#integer) [STRING](#string)
+
+A *checksum* is a native type (not implemented in PDL). See your generator documentation
+for more information on how to use it.
+
+The [integer](#integer) following the name specify the bit size of the checksum value.
+The [string](#string) following the size is a value defined by the generator implementation.
+
+```
+checksum CRC16: 16 "crc16"
+```
+
+### Custom Field
+
+> custom_field_declaration:\
+> &nbsp;&nbsp; `custom_field` [IDENTIFIER](#identifier) (`:` [INTEGER](#integer))? [STRING](#string)
+
+A *custom field* is a native type (not implemented in PDL). See your generator documentation for more
+information on how to use it.
+
+If present, the [integer](#integer) following the name specify the bit size of the value.
+The [string](#string) following the size is a value defined by the generator implementation.

+
+A *test* declares a set of valid octet representations of a packet identified by its name.
+The generator implementation defines how to use the test data.
+
+A test passes if the packet parser accepts the input; if you want to test
+the values returned for each field, you may specify a derived packet with field values enforced using
+constraints.
+
+```

+  pot: 8,
+  addition: CoffeeAddition
+}
+
+test Brew {
+  "\x00\x00",

+`T` can be:
+- An [integer](#integer) denoting the bit size of one element.
+- An [identifier](#identifier) referencing an [enum](#enum), a [struct](#struct)
+or a [custom field](#custom-field) type.
+

+
+```
+packet Brew {
+   pots: 8[2],
+   additions: CoffeeAddition[2],
+   extra_additions: CoffeeAddition[],

+
+> group_field:\
+> &nbsp;&nbsp; [IDENTIFIER](#identifier) (`{` [constraint_list](#constraints) `}`)?
+
+A *group* field inlines all the fields defined in the referenced group.
+
+If a [constraint list](#constraints) constrains a [scalar](#fields-scalar) field
+or [typedef](#fields-typedef) field with an [enum](#enum) type, the field will
+become a [fixed](#fields-fixed) field.
+The [fixed](#fields-fixed) field inherits the type or size of the original field and the
+value from the constraint list.
+
+See [Group Declaration](#group) for more information.
+
+### Size {#fields-size}
+
+> size_field:\
+> &nbsp;&nbsp; `_size_` `(` [IDENTIFIER](#identifier) | `_payload_` | `_body_` `)` `:` [INTEGER](#integer)
+
+A *\_size\_* field is a [scalar](#fields-scalar) field with as value the size in octet of the designated
+[array](#fields-array), [*\_payload\_*](#fields-payload) or [*\_body\_*](#fields-body).
+
+```
+packet Parent {
+  _size_(_payload_): 2,
+  _payload_

+[array](#fields-array).
+
+```
+packet Brew {
+  pot: 8,
+  _count_(additions): 8,
+  additions: CoffeeAddition[]
+}
+```
+
+### Payload {#fields-payload}
+
+> payload_field:\
+> &nbsp;&nbsp; `_payload_` (`:` `[` [SIZE_MODIFIER](#size-modifier) `]` )?
+
+A *\_payload\_* field is a dynamically sized array of octets.
+
+It declares where to parse the definition of a child [packet](#packet) or [struct](#struct).
+
+A [*\_size\_*](#fields-size) or a [*\_count\_*](#fields-count) field referencing
+the payload induce its size.
+
+If used, a [size modifier](#size-modifier) can alter the octet size.
+
+### Body {#fields-body}
+
+> body_field:\
+> &nbsp;&nbsp; `_body_`
+
+A *\_body\_* field is like a [*\_payload\_*](#fields-payload) field with the following differences:
+- The body field is private to the packet definition, it's accessible only when inheriting.
+- The body does not accept a size modifier.
+
+### Fixed {#fields-fixed}
+
+> fixed_field:\
+> &nbsp;&nbsp; `_fixed_` `=` \
+> &nbsp;&nbsp;&nbsp;&nbsp; ( [INTEGER](#integer) `:` [INTEGER](#integer) ) |\
+> &nbsp;&nbsp;&nbsp;&nbsp; ( [IDENTIFIER](#identifier) `:` [IDENTIFIER](#identifier) )
+
+A *\_fixed\_* field defines a constant with a known bit size.
+The constant can be either:

+- An [enum](#enum) tag
+
+```
+packet Teapot {
+  _fixed_ = 42: 8,
+  _fixed_ = Empty: CoffeeAddition
+}
+```
+
+### Checksum {#fields-checksum}
+
+> checksum_field:\
+> &nbsp;&nbsp; `_checksum_start_` `(` [IDENTIFIER](#identifier) `)`
+
+A *\_checksum_start\_* field is a zero sized field that acts as a marker for the beginning of
+the fields covered by a checksum.
+
+The *\_checksum_start\_* references a [typedef](#fields-typedef) field
+with a [checksum](#checksum) type that stores the checksum value and selects the algorithm
+for the checksum.
+
+```
+checksum CRC16: 16 "crc16"
+
+packet CRCedBrew {
+  crc: CRC16,
+  _checksum_start_(crc),
+  pot: 8,
+}
+```
+
+### Padding {#fields-padding}
+
+> padding_field:\
+> &nbsp;&nbsp; `_padding_` `[` [INTEGER](#integer) `]`
+
+A *\_padding\_* field immediately following an array field pads the array field with `0`s to the
+specified number of **octets**.
+
+```
+packet PaddedCoffee {
+  additions: CoffeeAddition[],
+  _padding_[100]
+}
+```
+
+### Reserved {#fields-reserved}
+
+> reserved_field:\
+> &nbsp;&nbsp; `_reserved_` `:` [INTEGER](#integer)

+//! Rust no-allocation backend
+//!
+//! The motivation for this backend is to be a more "idiomatic" backend than
+//! the existing backend. Specifically, it should
+//! 1. Use lifetimes, not reference counting
+//! 2. Avoid expensive memory copies unless needed
+//! 3. Use the intermediate Schema rather than doing all the logic from scratch
+//!
+//! One notable consequence is that we avoid .specialize(), as it has "magic" behavior
+//! not defined in the spec. Instead we mimic the C++ approach of calling tryParse() and
+//! getting a Result<> back.

+# RootCanal
+
+RootCanal is a virtual Bluetooth Controller.
+Its goals include, but are not limited to: Bluetooth Testing and Emulation.
+
+## Usage
+
+RootCanal is usable:
+- With the Cuttlefish Virtual Device.
+- As a Host standalone binary.
+- As a Bluetooth HAL.
+- As a library.
+
+### Cuttlefish Virtual Device
+
+Cuttlefish enables RootCanal by default, refer to the Cuttlefish documentation
+for more informations
+
+### Host standalone binary
+
+```bash
+m root-canal # Build RootCanal
+out/host/linux-x86/bin/root-canal # Run RootCanal
+```
+
+Note: You can also find a prebuilt version inside [cvd-host_package.tar.gz from Android CI][cvd-host_package]
+
+[cvd-host_package]: https://ci.android.com/builds/latest/branches/aosp-master/targets/aosp_cf_x86_64_phone-userdebug/view/cvd-host_package.tar.gz
+
+RootCanal when run as a host tool, exposes 4 ports by default:
+- 6401: Test channel port
+- 6402: HCI port
+- 6403: BR_EDR Phy port
+- 6404: LE Phy port
+
+### Bluetooth HAL
+
+A HAL using RootCanal is available as `android.hardware.bluetooth@1.1-service.sim`
+
+## Channels
+
+### HCI Channel
+
+The HCI channel uses the standard Bluetooth UART transport protocol (also known as H4) over TCP.
+You can refer to Vol 4, Part A, 2 of the Bluetooth Core Specification for more information.
+Each connection on the HCI channel creates a new virtual controller.
+
+### Test Channel
+
+The test channel uses a simple custom protocol to send test commands to RootCanal.
+You can connect to it using [scripts/test_channel.py](scripts/test_channel.py).
+
+### Phy Channels
+
+The physical channels uses a custom protocol described in [packets/link_layer_packets.pdl](packets/link_layer_packets.pdl)
+with a custom framing.
+**Warning:** The protocol can change in backward incompatible ways, be careful when depending on it.
