Android Question Bluetooth communication protocol

[Rainer@B4A]

Hi,
for my outdoor app I need some external pushbuttons.
I believe the bluetooth headset adapters below will give me this functionality.

It's easy to find and connect the device with BluetoothAdmin + Serial.
They even start communication be sending "AT+BRSF=25" to my app.

Is there an expert in our community who knows the protocol and can help me to go on ?

Another approach may be emulate an audio app like jukebox, because they work perfectly with these devices.
But the B4A MediaPlayer don't fit.

Thanks
Rainer

You should use an intent filter for that as the headset events are handled by the system.

Start with this tutorial: Intent Filters - Intercepting SMS messages in the background

The action should be one of these actions:
