I currently have my RPi streaming audio from a hifiberry add line one to a headset A2DP profile. I would like to simultaneously connect an android phone to the RPi and send data messages to a running java program. The goal is to control Pulse audio's volume, source etc from the phone whilestreaming.
This requires two Bluetooth connections from different devices and with different profiles. I know how to connect phone and java program via BT for messaging but I'm not sure if the audio streaming will prevent my data connection.
Anyone have experience in this area?
