. For your information my environment details are as follows:

1. Board          iMX6Q-AI

2. OS              Marshmallow 6.0.1

3. Kernel         linux 3.14.52

4. WiFi H/W    Murata WiFi-BT V2 adaptor

For more on this i am attaching the image of my hardware setup. Look forward for your support.

Thank you in advance.

Hello Rohit,

     I don't have detailed documents on how to porting bluetooth for you. I checked android5.1.1 source code on sabresd_mx6dq board, in BoardConfig.mk, BCM4339 BT has beed supported, see following:

---------------------------------

# Broadcom BCM4339 BT
BOARD_HAVE_BLUETOOTH_BCM := true
BOARD_BLUETOOTH_BDROID_BUILDCFG_INCLUDE_DIR := device/fsl/sabresd_6dq/bluetooth

USE_ION_ALLOCATOR := false
USE_GPU_ALLOCATOR := true

---------------------------------

So it is no any problem for you to refer to BT source code for sabresd_mx6dq board, check Marshmallow 6.0.1 source code for sabresd_mx6dq board, please! then move corresponding source code to your board!

Best Regards,

Weidong

Hello Wigros San,

Thank you for your reply.

As suggested i referred  the SD BT code and made the required changes for iMX6Q-AI board. One good thing is now WiFi-BT is working fine on my AI board with Marshmallow.

Currently I am able to transfer image, play media over Bluetooth on my board. But it is through the A2dpsink app (System app) given as part of Android BSP.

Now, further to this I want to achieve the functionality of HFP and A2dp for which want to develop a Android application, but while doing this I am facing below issues:

1. two class (import android.bluetooth.BluetoothA2dpSink and import android.bluetooth.BluetoothAvrcpController)files is not getting import in Android studio.

The source code of Android application i am referring is here .

Could you please guide me on this to realize the hansfree and A2dp functionality on my AI Board.

Thank you,

Rohit
