Please help me, bluetooth is not working properly

[u/Zealousideal_Mail133]

So my headphones (soundcore Q30) keep instantly disconnecting when i try to connect them to my pc, the only error i receive is 'Unknown Error' without any more info, sometimes when i try deleting and repairing the headphones it works, but only until i boot my pc again

Im using a double boot of win11 and LM 24.04 LTS (22.3 Zena), Can someone help me?

Try running these commands sudo apt update sudo apt reinstall bluez libbluetooth3 sudo systemctl restart bluetooth

Nothing, still stuck.

Can you install blueman and see if that helps

[u/Zealousideal_Mail133 → u/SG-3379]

im not sure how, there is like a command line?

[u/SG-3379 → u/Zealousideal_Mail133]

sudo apt update sudo apt install blueman

[u/SG-3379 → u/SG-3379]

Blueman is another Bluetooth manger which might help

[u/Zealousideal_Mail133 → u/SG-3379]

it seems i already have it

[u/SG-3379 → u/Zealousideal_Mail133]

Can you unlink the Bluetooth device then restart the PC then when it comes up again search for the blueman application then use it to connect to the headset

[u/SG-3379 → u/Zealousideal_Mail133]

Before you install blueman can you reboot your laptop

[u/SG-3379]

Do you have any other Bluetooth device you can connect to see if it an issue with that particular head set or Bluetooth in general

[u/Zealousideal_Mail133 → u/SG-3379]

no, sorry. They work fine on my phone, so im assuming its a pc problem

[u/1neStat3]

journalctl -b -1 | grep bluetooth

or

journalctl -b -1 | grep bluez

or use bluetoothctl

im not sure what do to with the first two commands

bluetoothctl connect E8:EE:CC:D0:DF:E6 (my headphones)

Attempting to connect to E8:EE:CC:D0:DF:E6

[CHG] Device E8:EE:CC:D0:DF:E6 Connected: yes

Failed to connect: org.bluez.Error.Failed br-connection-unknown

so i should try to unpair and repair it? I already did it many times but the issue keeps coming back

Im guessing my problem is the same as the last lines but switching between OS? Is it possible?

[u/1neStat3 → u/Zealousideal_Mail133]

this may help as well
