Bluetooth making me lose my mind

I've always had many issues with bluetooth on Linux, but it is getting so much worse lately.

Let me start with the fact that my headphones often had problems and sometimes did not connect, but usually worked pretty well.

2 days ago the bluetooth adapter started to not get recognized anymore and required me to reset the cmos, but after doing so I had bluetooth working one time, after which I got a long series of different random errors when trying to connect to my headphones (br-connection-canceled; br-connection-refused; br-profile-unknown; ..........) while they work fine with my phone.
Now, apparently, bluez refuses to work decently....

bluetoothctl power on; bluetoothctl connect XX:XX:XX:XX:XX:XX

Failed to set power on: org.bluez.Error.Busy
Attempting to connect to XX:XX:XX:XX:XX:XX
Failed to connect: org.bluez.Error.NotReady br-connection-adapter-not-powered

Would love to see those working decently...

Re: Bluetooth making me lose my mind

Can you run `journalctl -f -u bluetooth` in one terminal and `bluetoothctl connect XX:XX:XX:XX:XX:XX` in second one to doublecheck messages in log? Systemctl status tend to misslead sometime as real log messagess could be burried deeper, you can see that all messages in status are from same second and only last X is displayed.

Your problem may be different, but I just got same `org.bluez.Error.NotReady br-connection-adapter-not-powered`. There was following in logs:

❯ jc -f -u bluetooth.service

Connection refused seems clear enough, I had to repair and everything is working now. Not sure if it will be making troubles. I don't have really enjoyable experience, not sure if it is since I started hibernating pc or since dualbooting to windows and sharing bt key...
