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.

TODO(abhishekpandit) - Provide a pre-packaged option for these or proper build instructions from source.

  • libchrome
  • modp_b64
  • tinyxml2

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
