Revert "Bluetooth: Fix the issue that peer A2DP SNK device can not auto-reconnect."

This reverts commit 5db07990d36ab326421b6641628f110ec0485dda.

Despite the original patch intention, it actually causes various remote
devices (tested Android Auto, Logitech Speakerphone, Tesla Model S and
many more) to no connect A2DP (only HFP) in various re-connect
scenarios.

This is due to the fact that the stream end point type is not correctly
determined yet in some of these scenarios causing the AVDT stream to be
closed prematurely and thus the A2DP connection to fail.

Test: manual; various devices

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/packages/modules/Bluetooth/system

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
git clone https://android.googlesource.com/platform/hardware/libhardware

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

Generate your build files

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
