Hi,
Please go to Settings > Bluetooth and Devices > Devices > More devices and Printer Settings.
- Find your EDIFIER R1280DB under Devices
- Right-click on it → Properties
- Go to the Services tab
There you should see a list of Bluetooth profiles/services like:
- Handsfree Telephony
- Headset
- Audio Sink (A2DP)
- Remote Control, etc.
I’m eager to hear back and work together to find a solution.
