Bluetooth on UBUNTU 20.04 constantly disconnecting
Solution 1:
I had the same problem. Found the solution here on Reddit Disconnect your devices entirely first before trying these steps:
Run
bluetoothctl
You will get a new prompt, at which you should enter
agent on
default agent
And then, using the MAC address (a long string of colon-separated pairs of alphanumeric characters, something like 11:BB:3C:44:5E:FF:7G) of the device to connect to (you should be able to find it by typing devices at this prompt), run
trust <MAC>
pair <MAC>
connect <MAC>
