I've been unsuccessful to pair with 2 different bluetooth mice. However bluetooth seems to work with other devices. I'm under the impression that this problem only happens with Bluetooth LE devices. Trying to pair using bluetoothctl fails with the org.bluez.Error.AuthenticationCanceled error: [bluetooth]# pair E5:5B:67:2A:09:76 Attempting to pair with E5:5B:67:2A:09:76 [CHG] Device E5:5B:67:2A:09:76 Connected: yes [CHG] Device E5:5B:67:2A:09:76 Connected: no Failed to pair: org.bluez.Error.AuthenticationCanceled A quick google search for org.bluez.Error.AuthenticationCanceled reported nothing relevant. Running btmon while trying to pair with the device gives me the following: Bluetooth monitor ver 5.53 = Note: Linux version 5.4.0-40-generic (x86_64) 0.998188 = Note: Bluetooth subsystem version 2.22
