Separated initialize and re-initialize of DM control block

Use Case: Turning ON Bluetooth failed after network reset

Steps:
1. Turn ON Bluetooth
2. Go to settings->backup and restore->network reset.
3. Do reset to reset BT, WIFI, data.
4. Go back to Bluetooth settings menu and try to turn ON Bluetooth.

Failure: Bluetooth is not turning ON after network reset

Root Cause: In case BTA_SYS_HW_OFF_EVT event, alarm_new is getting called.
Which is causing issue in Next Turn ON of Bluetooth if PID is same.

Fix: Separated initialize and re-initialize of DM control block

Test: code compilation.

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
