My problem is fairly simple. I have a pair of Q30 headphones that I'm trying to pair to my desktop. I have a bluetooth 5.2 bluetooth card which I believe (but don't truly know) is backwards-compatible with Q30's bluetooth 5. My bluetooth definitely works, as I was able to pair my phone with it, but for some reason my Q30s refuse to pair.
- Desktop Software/Hardware:
- Linux kernel version: 5.15.0-46-generic
- Ubuntu version: Ubuntu 22.04.1 LTS
- Bluetooth version: 5.2
- Device driver: Intel® Wi-Fi 6 AX210 160MHz
Before, when I clicked on Pair, it would replace the label of the device with "BES_BLE" (a known bug). After some time giving me the spinner, the device would disappear from the list and then reappear unconnected. Rebooting both my desktop and my headphones did not work. I also have no other devices connected to my headphones before attempting to pair to my desktop.
The closest thread I could find that was related to this was here but it seems like no solution was found.
One last thing I tried was connecting via commandline. I used hcitool scan to find the MAC address of the headphones and bluetooth ctl connect [MAC address]. This gave me the following error: Failed to connect: org.bluez.Error.Failed br-connection-unknown. Not very helpful
