Clear BLE block from device records at unpair Use Case: Pair and unpair LE remote device repeatedly. The repair intermittently fails with the error "DHKey Check Failure" Failure: Pairing failure is observed when pairing is performed after unpairing, without performing a BT reset. Further analysis of the SMP logs indicate that DUT uses the static address of the remote device for calculation of the MacKey value. At the time of pairing, the remote RPA should be used (and the static address has not yet been distributed either). The problem is caused by the previous dev record which is left in the stack, and at the time of repair, stack picks the old device record and reuses it. Fix: This change removes the entire BLE block from the device record, after the unpairing is performed, so that a new device record is allocated, after the repairing is done.

Just build AOSP - Fluoride is there by default.
Instructions for Ubuntu, tested on 15.10 with GCC 5.2.1.
sudo apt-get install libevent-dev
sudo apt-get install ninja-build
or download binary from https://github.com/ninja-build/ninja/releases
Get sha1 of current version from here and then download corresponding executable:
wget -O gn http://storage.googleapis.com/chromium-gn/<gn.sha1>
i.e. if sha1 is “3491f6687bd9f19946035700eb84ce3eed18c5fa” (value from 24 Feb 2016) do
wget -O gn http://storage.googleapis.com/chromium-gn/3491f6687bd9f19946035700eb84ce3eed18c5fa
Then make binary executable and put it on your PATH, i.e.:
chmod a+x ./gn sudo mv ./gn /usr/bin
mkdir ~/fluoride cd ~/fluoride git clone https://android.googlesource.com/platform/system/bt
Then fetch third party dependencies:
cd ~/fluoride/bt mkdir third_party cd third_party git clone https://github.com/google/googletest.git git clone https://android.googlesource.com/platform/external/libchrome git clone https://android.googlesource.com/platform/external/modp_b64 git clone https://android.googlesource.com/platform/external/tinyxml2
And third party dependencies of third party dependencies:
cd fluoride/bt/third_party/libchrome/base/third_party mkdir valgrind cd valgrind curl https://chromium.googlesource.com/chromium/src/base/+/master/third_party/valgrind/valgrind.h?format=TEXT | base64 -d > valgrind.h curl https://chromium.googlesource.com/chromium/src/base/+/master/third_party/valgrind/memcheck.h?format=TEXT | base64 -d > memcheck.h
Fluoride currently has dependency on some internal Android projects, which also need to be downloaded. This will be removed in future:
cd ~/fluoride git clone https://android.googlesource.com/platform/system/core git clone https://android.googlesource.com/platform/hardware/libhardware git clone https://android.googlesource.com/platform/system/media
We need to configure some paths to make the build successful. Run:
cd ~/fluoride/bt gn args out/Default
This will prompt you to fill the contents of your “out/Default/args.gn” file. Make it look like below. Replace “/home/job” with path to your home directory, and don't use “~” in build arguments:
# Build arguments go here. Examples: # is_component_build = true # is_debug = false # See "gn args <out_dir> --list" for available build arguments. libhw_include_path = "/home/job/fluoride/libhardware/include" core_include_path = "/home/job/fluoride/core/include" audio_include_path = "/home/job/fluoride/media/audio/include"
Then generate your build files by calling
cd ~/fluoride/bt gn gen out/Default
cd ~/fluoride/bt ninja -C out/Default all
This will build all targets (the shared library, executables, tests, etc) and put them in out/Default. To build an individual target, replace “all” with the target of your choice, e.g. ninja -C out/Default net_test_osi
.
cd ~/fluoride/bt/out/Default LD_LIBRARY_PATH=./ ./bluetoothtbd -create-ipc-socket=fluoride
