Background:
I’m looking to enable A2DP audio streaming SINK support on my Nexus 4 & 5 devices (running Lollipop) . I also need concurrent SPP/RFCOMM bidirectional traffic for my application command and control. I’ll be sending serial traffic to a microcontroller via a Bluetooth module (such as the BlueGiga WT32i or ) which will be controlling various other hardware. As such, I believe AVRCP isn’t up to the task.
Question:
Has anyone enabled A2DP SINK support in Android (Target Lollipop or earlier) and either successfully got an concurrent SPP/RFCOMM channel working OR can offer options on how to achieve this?
