How to enable HFP in the device mode


#1

Hi,
In the device mode HFP, I am able to establish a call using alsa tools (arecord and aplay), it is working fine. But it is not working through BT stack, data is not coming to primary HAL. But A2DP is working fine, can someone help me out in this. Thanks in advance
