eatt: Improve handling incoming EATT connection

With this patch we make sure that eatt_dev is created always when EATT
is supported on the peer side, no matter what is the connection role.

It will allow to accept ecoc channels when Android device is peripheral
device

Fluoride Bluetooth stack

Building and running on AOSP

Just build AOSP - Fluoride is there by default.

Building and running on Linux

Instructions for a Debian based distribution:

  • Debian Bullseye or newer
  • Ubuntu 20.10 or newer
  • Clang-11 or Clang-12
  • Flex 2.6.x
  • Bison 3.x.x (tested with 3.0.x, 3.2.x and 3.7.x)

You‘ll want to download some pre-requisite packages as well. If you’re currently configured for AOSP development, you should have all required packages. Otherwise, you can use the following apt-get list:

sudo apt-get install repo git-core gnupg flex bison gperf build-essential \
  zip curl zlib1g-dev gcc-multilib g++-multilib \
  x11proto-core-dev libx11-dev lib32z-dev libncurses5 \
  libgl1-mesa-dev libxml2-utils xsltproc unzip liblz4-tool libssl-dev \
  libc++-dev libevent-dev \
  flatbuffers-compiler libflatbuffers1 \
  openssl openssl-dev

You will also need a recent-ish version of Rust and Cargo. Please follow the instructions on Rustup to install a recent version.

Download source

mkdir ~/fluoride
cd ~/fluoride
git clone https://android.googlesource.com/platform/packages/modules/Bluetooth/system

Install dependencies (require sudo access). This adds some Ubuntu dependencies and also installs GN (which is the build tool we're using).

cd ~/fluoride/bt
build/install_deps.sh

The following third-party dependencies are necessary but currently unavailable via a package manager. You may have to build these from source and install them to your local environment.

  • libchrome
  • modp_b64

We provide a script to produce debian packages for those components, please follow the instructions in build/dpkg/README.txt.

The googletest packages provided by Debian/Ubuntu (libgmock-dev and libgtest-dev) do not provide pkg-config files, so you can build your own googletest using the steps below:

$ git clone https://github.com/google/googletest.git -b release-1.10.0
$ cd googletest        # Main directory of the cloned repository.
$ mkdir build          # Create a directory to hold the build output.
$ cd build
$ cmake ..             # Generate native build scripts for GoogleTest.
$ sudo make install -DCMAKE_INSTALL_PREFIX=/usr

Stage your build environment

For host build, we depend on a few other repositories:

Clone these all somewhere and create your staging environment.

export STAGING_DIR=path/to/your/staging/dir
mkdir ${STAGING_DIR}
mkdir -p ${STAGING_DIR}/external
ln -s $(readlink -f ${PLATFORM2_DIR}/common-mk) ${STAGING_DIR}/common-mk
ln -s $(readlink -f ${PLATFORM2_DIR}/.gn) ${STAGING_DIR}/.gn
ln -s $(readlink -f ${RUST_CRATE_DIR}) ${STAGING_DIR}/external/rust
ln -s $(readlink -f ${PROTO_LOG_DIR}) ${STAGING_DIR}/external/proto_logging

Build

We provide a build script to automate building assuming you've staged your build environment already as above.

./build.py --output ${OUTPUT_DIR} --platform-dir ${STAGING_DIR} --clang

This will build all targets to the output directory you've given. You can also build each stage separately (if you want to iterate on something specific):

  • prepare - Generate the GN rules
  • tools - Generate host tools
  • rust - Build the rust portion of the build
  • main - Build all the C/C++ code
  • test - Build all targets and run the tests
  • clean - Clean the output directory

You can choose to run only a specific stage by passing an arg via --target.

Currently, Rust builds are a separate stage that uses Cargo to build. See gd/rust/README.md for more information.

Run

By default on Linux, we statically link libbluetooth so you can just run the binary directly:

cd ~/fluoride/bt/out/Default
./bluetoothtbd -create-ipc-socket=fluoride
