(Get the code!)
I'm using Ubuntu 20.04 on a Huawei Matebook 13 AMD laptop which seems to use a Realtek RTL8822CE Wifi/Bluetooth combo adapter.
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.
[bluetooth]# pair 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.
A quick google search for org.bluez.
Running btmon while trying to pair with the device gives me the following:
