I’ve been trying for a while to connect my Bose QuietComfort Headphones to my Lenovo ThinkPad T14 Gen 5 AMD laptop, but it just doesn’t work. I can successfully pair them using bluetoothctl, but when I try to connect it seems to time out.
I’m a bit lost at what might be the issue here. I’ve tested with my desktop PC that has Pop OS, and there headphones connected instantly.
Maybe it’s because of the hardware (Qualcomm) being too new?
I’d appreciate some pointers or hints. Thank you.

In case the way to get a device properly paired it could be needed to remove first with the GUI from your Desktop from known devices and start over manually with sudo bluetoothctl
set BT Headphones into pairing mode
and follow this:
sudo bluetoothctl
scan on
wait for the device to show up: [bluetooth]# [NEW] Device XX:XX:XX:XX:XX:XX Bose XYYZ
and run:
pair XX:XX:XX:XX:XX:XX
wait till prompt again shows: [bluetooth]# instead of the Headphone Name…
and run: connect XX:XX:XX:XX:XX:XX
Kinda similar thing happens now. I can pair, but when I connect it stays on the [Bose QC Headphones] and just shows [CHG] / [NEW] / [DEL] without an end of other devices nearby.
Also, some new errors in the service logs:
Nov 06 22:40:39 lenovo bluetoothd[676]: src/profile.c:record_cb() Unable to get Hands-Free Voice gateway SDP record: Host is down
Nov 06 22:40:40 lenovo bluetoothd[676]: profiles/deviceinfo/deviceinfo.c:read_pnpid_cb() Error reading PNP_ID: Invalid pdu length received
It kinda connects, but not really, without any options to change output
not much to find about… always a bit tricky with BT devices. BT version 5+ is still a little issue on Linux have two the older one works the one with very latest features simply does not work… similar to your issue.
in case Gnome BZT settings are problematic in addition so also try to use pavucontrol to set to the SBC mode could help and indeed running bluetoothctl as root…
In case check boot log:
Now it doesn’t want to connect through GUI at all, it tries to load but then turns off. Probably it never completed a proper connection in the first place.

Tried it, without anything new. What is interesting is that it showed error updating services in the logs and paired successfully in bluetoothctl at the same time, but then after couldn’t connect as usual.

on researching output people mostly can use device after removing repairing it…
Could be also the issue is not BT and it is about the audio connection… or in general something with the features not working properly what causes to fail to connect audio device… to pipewire…
in /etc/bluetooth/main.conf
you have a lot of options to be set… #KernelExperimental = false
to KernelExperimental = true
Thanks, I’ll check the main.conf out. I did experiment with it by turning “bredr” mode only instead of default “dual”, but it’s as you’ve said, most likely the audio part that can’t get configured.
Do you think it’s risky to try installing aur linux-firmware instead of the core that I have at the moment? They are only 5 days apart though (core: 20241017.22a6c7dc-1 vs aur: 20241022.e1d95775-1).
I also checked the aur/broadcom-bt-firmware, but I’m not sure it’s suitable for my hardware.
I do use linux-firmware-git here without any issues … in case you can simply reinstall the core package to replace it genertal it should not cause boot stop if it would not work properly… and it is always a good idea to keep an usb installer at hand on arch to be able to arch-chroot in case: https://discovery.endeavouros.com/system-rescue/arch-chroot/2022/12/
Best stable thing you can have …
