[SOLVED] bluetooth headset not pairing properly

p_noumenon · 2024-12-17 11:07:44

Trying to get a bluetooth headset to work, but struggling. I've enabled bluetooth and found the device, and seemingly paired with it:

[bluetooth]# pair CF:84:84:F8:97:2B
Attempting to pair with CF:84:84:F8:97:2B
[P47]# Pairing successful

Doing

devices Paired

now shows

Device CF:84:84:F8:97:2B P47

However, the headset itself does not show the expected sign of being paired (according to the manual, a slow blinking), and it's not detected in the sound settings at all, even after restarting PulseAudio. In fact, after a while it turns off automatically (yet is still listed as paired in bluetoothctl, leading me to suspect that that's not a valid indicator of the active pairing status.

Any help appreciated.

Check your journal on what happened with the device, is pulseaudio-bluetooth installed (... and wireplumber not installed?) What outputs do you get from

sudo journalctl -b | curl -F 'file=@-' 0x0.st
systemctl --user status pulseaudio pipewire wireplumber
pactl list cards

FWIW generally speaking pipewire is likely to have the more complete BT stack implementation, so you might want to switch to it by installing wireplumber and pipewire-pulse in lieu of the pulseaudio packages.

Not sure how helpful that first one is due to how comprehensive it is, but here it is.

The second one gives this (never heard of wireplumber):

Is it really the audio that's the problem, though? Seemed like the pairing itself wasn't working properly, since the headset didn't show the expected signs of it, but I'm certainly no expert on the matter.

EDIT:

Solved this now. As suspected the problem was upstream from the audio itself, and with the pairing. Turns out you also have to trust the device (in bluetoothctl), and as long as bluetooth was on with the device both paired and trusted, it connected. As far as I understand you can also manually connect to it after trusting it if the device is already on as you trust it (it didn't connect until it turned off from timing out and I turned it on again, at least).
