Updated the A2DP statistics

 * Added "Frame expected" and "Frames limited" statistics in the
   bugreport about expected and limited number of frames per tick.
   Also, added corresponding "Counts (expected/limited)":

A2DP State:
  TxQueue:
  Counts (enqueue/dequeue/readbuf)                        : 386 / 386 / 768
  Last update time ago in ms (enqueue/dequeue/readbuf)    : 12644 / 12643 / 12600
  Frames expected (total/max/ave)                         : 2632 / 8 / 6
  Frames limited (total/max/ave)                          : 0 / 0 / 0
  Counts (expected/limited)                               : 382 / 0
  Frames per packet (total/max/ave)                       : 2618 / 7 / 6
  ...

 * Renamed "tx_queue_max_frames" to "tx_queue_max_frames_per_packet"

 * Fixed the computation of actual transmitted frames:
   tx_queue_total_frames, tx_queue_max_frames_per_packet

 * Computed / added buffer_overruns_max_count and
   buffer_underruns_average to the Protobuf stats.

Fluoride Bluetooth stack

Building and running on AOSP

Just build AOSP - Fluoride is there by default.

Building and running on Linux

Instructions for Ubuntu, tested on 15.10 with GCC 5.2.1.

Install required libraries

sudo apt-get install libevent-dev

Install build tools

  • Install ninja build system
sudo apt-get install ninja-build

or download binary from https://github.com/ninja-build/ninja/releases

  • Install gn - meta-build system that generates NinjaBuild files.

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

Download source

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

Configure your build

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

Build

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.

Run

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