Restart sniff timer on AVDTP signalling channel establishment

VolksWagan UHV Preminum takes time to initiate AVDTP media channel
after AVDTP signalling channel is up. If mentioned duration exceeds
7 seconds then ACL link goes into sniff due to which A2dp Connection
fails.

With this change we make sure that when AVDTP signalling channel
is up and media channel is not connected we do not go to sniff,
which is achieved by restarting sniff timer on signalling channel up
so that link does not go to sniff in between ongoing connection.

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
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
