How to pair+setup+connect airpod pro on ubuntu 20.04

I am using Ubuntu 20.04 and i own a pair of Airpod pro's.

Ubuntu detects the device but fails to pair/setup/connect. I know this because when i click it, it has a spinning logo like its attempting to connect and then it just returns back to the default "Not Set Up".

I have followed advice from here setting the ControllerMode, i have tried both "dual" and "le" without any success.

kay@khan:~$ sudo /etc/init.d/bluetooth status

Solution 1:

Short answer is: use ControllerMode = bredr as discussed here

For others:

1. Set ControllerMode = bredr by editing /etc/bluetooth/main.conf file using sudo nano /etc/bluetooth/main.conf command (or another text editor of your choice)
2. sudo /etc/init.d/bluetooth restart
3. Try to pair again.

Solution 2:

Steps to resolve the issue:

1. sudo nano /etc/bluetooth/main.conf
2. Set ControllerMode = dual

I had to set dual because my Bluetooth mouse was not being detected if I assign bredr.

With dual I can use both my wireless Bluetooth earphones as well as Bluetooth mouse simultaneously.
