Fix pairing state change in collision scenario

DUT Stuck in pairing state forever with selfy stick
during repair.

1. Pair and connect remote devices with DUT.
2. Now un pair selfy stick from DUT.
3. Keep remote in discoverable mode.
4. Start inquiry and try to pair with device.

Pairing with selfy stick always fails after collision.

Root Cause:
As we return from btm_sec_dd_create_conn with out
moving pairing state in connection collision scenario. Pairing
state will remains idle and pairing won't proceed further.

Move the pairing state in collision scenario so that pairing
can proceed further.

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

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

Get sha1 of current version from here and then download corresponding executable:

wget -O gn<gn.sha1>

i.e. if sha1 is “3491f6687bd9f19946035700eb84ce3eed18c5fa” (value from 24 Feb 2016) do

wget -O gn

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

Then fetch third party dependencies:

cd ~/fluoride/bt
mkdir third_party
cd third_party
git clone
git clone
git clone
git clone

And third party dependencies of third party dependencies:

cd fluoride/bt/third_party/libchrome/base/third_party
mkdir valgrind
cd valgrind
curl | base64 -d > valgrind.h
curl | 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
git clone
git clone

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/” 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


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.


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