I acquired a Blaupunkt BLP6100 Bluetooth speaker. Which turns out to support the following services via bluetooth:
That last one I did not expect. I have tried opening the port with minicom and it will say carrier detect but sofar trying to wake it at 115200 or 9600 hasn't resulted in anything.

- Headset (audio for phone calls)
- Handsfree operation (use buttons to accept, hangup or reject calls)
- Audio sink (the main function of a bluetooth speaker)
- Serial port
