Unable to connect to the Bluetooth device

Hey guys,

For a while now I am facing issues with the Bluetooth devices with one of my laptops. Most of the time I am unable to connect to the Bluetooth device and after restarting the Bluetooth service a couple of times when I do if I am not playing anything it gets disconnected every time!! The other laptop also running arch was able to connect to the Bluetooth device flawlessly, so I thought it's my setup problem then I did a clean install but with the same results.

When I am checking the logs of the Bluetooth service when I am facing issues I often see this:

Nov 24 19:56:06 undercroft bluetoothd[467]: src/profile.c:record_cb() Unable to get Headset Voice gateway SDP record: Software caused connection abort

Systemctl full logs:

❯ sudo journalctl -u bluetooth.service -b

Re: Unable to connect to the Bluetooth device

If you have consistent software configuration between two systems, and one works but the other doesn't, then it's likely to be driver- or hardware-related.

So, some pointers: Is it a driver issue (have you tried switching between linux and linux-lts if it's an in-kernel module)? Do you have a hybrid wifi-BT card? Is it radio interference between 2.4GHz wifi and BT?
