I'm trying to get a USB bluetooth device (0a12:0001) to work, without success.
After boot, `hciconfig -a` shows hci0 as DOWN. I can manually `hciconfig hci0 up`. `hcitool scan` and `hcitool lescan` both show results if there are bluetooth devices in range.
However, I can't pair to them.
hcitool cc 00:16:94:3D:7C:AE ; hcitool auth 00:16:94:3D:7C:AE
`HCI authentication request failed: Connection timed out`
If I try to use bluetooth in the android GUI or in an app, it does not find any device.
I'm in a QEMU VM. I also tried bluetooth in a VirtualBox installation, which did not work either. I use Android 10 x86_64.
I'm not too experienced with Android. My goal is to run a specific app, Aerophone mini Plus. Can anyone help?
