Not able to access Mic from Android Application

[vishalgautam]

Hello Experts,

I have ported recently ported bluedroid to iMX6Q-AI board. Below is the software stack of mine:

OS:- Android Marshmallow 6.0.1

Kernel:- 3.14.52

U-boot:- 2015.04

Here, i want to realize BT HFP  profile. in order to get this i connect mic to J26(1). With this i am not able to record from mic as expected(no data). Instead i am getting data from J26(2). 

Also, i observed that i am able to record voice through sound recored app provided in BSP through J26(2) instead of J26(1).

I am attaching adb logcat and the Android application i developed for the purpose.

Please help me with this else it will be great if you can share me some application code like A2dpSink you have provided in BSP to realize HFP (call functionality).

Thank you,

Vishal

Hi Wigros,

We are still waiting for your response.

We have ported bluedroid to iMX6Q-AI board. We are using BT calling functionality. In current scenario we are able to call through bluetooth paired device from sabreauto board. But the issue is that after the call is attend caller and receiver are not able to hear the voice of each other.

It seems audio routing is not happening.

Please provide the solution for the same.
