I'm on a Kali (4.18.0-kali3-amd64) and I have an issue with my headsets when I pair them with the internal bluetooth of my computer : it disconnects itself when they're not in use continuously.
service bluetooth status
Returns when it happens :
déc. 20 17:36:56 localhost bluetoothd: Start: Connection timed out (110) déc. 20 17:36:56 localhost bluetoothd: avdtp_start failed déc. 20 17:36:56 localhost bluetoothd: Transaction label doesn't match
I can redo the pairing but the issue persists and I've search solution about avdtp_start but none are about this specific issue.
