The situation is this:
- I use a bluetooth dongle ASUS UB400 on my PC, bluetooth version 4.0
- My Sony wh-1000xm5 (bluetooth version 5.3) is not detected by the PC when I scan for new bluetooth devices
- Another Anker Soundcore Q20 headphones are detected and working fine, like the mouse and a bluetooth speaker.
- The Sony is detected by my android smartphones and working fine
- I switched the dongle with another one with different brand, and all the devices were detected (and work fine) with the excepcion of the Sony.
- Using Debian 12.8 and tested with bluetoothctl
Any advice is welcome.
Did you happen to enable Bluetooth LE-Audio mode for the Headphones in an app? If so you need to turn it off.
