Unstable bluetooth

General system Gaming, sound and video
1

Hi,

I started using EndeavourOS about 2 months and I got an issue that I tried to resolve but can’t resolve.

I got unstable bluetooth, when I connect my headphone it crash.

What happen exactly : What ever Im doing, after 5-30 minutes, my sound cut but the bluetooth connection is still marked as “Connected”. It’s only after 10 seconds that the bluetooth connection is stopped and restarted over and over again.

I tried to see if the headphone was the problem on another computer and it works without any problem.

you should check and see if there is an update for your bios

I have updated my BIOS from F.51 to F57 (latest available) but now I can’t even connect my headphone in bluetooth.

I had some BT issues at work on a Lenovo laptop with an Intel AX210 WIFI adapter, I think it is? It’s a combo WIFI/BT wireless adapter in a laptop.

I used this URL to get enough tips to resolve the issue: now everything connects fine for me–my mouse and JBL earbuds and a BlasterX gaming headset.

HOWEVER: the laptop is Linux certified so the drivers are all there. I am unsure about your device but you might want to take a look at what helped me:

EDIT: obviously the Ubuntu specific stuff won’t work for you on Endeavour OS, but I HAD to say it.

Are you using Gnome? If so, there is a known problem I documented a while back: Crash with Bluetooth headphones after Wireplumber 5.13-1 update

If this is the case, you will need to downgrade wireplumber & libwireplumber until a fix is worked out.

Hmmm…I see you are on KDE, but you might still do a downgrade to see if that “fixes” your problem.

I see your issue involves the same handoff problem. Follow the links in my post to see what is going on.

Hi,

thanks for the documentation, it seems that it has solved the problem.

Im gonna try fully tomorrow and be sure that it not crash but I think you solved it. Thank you!

No problem….I’ve been seeing that quite a bit after the update….I’m following the “fix” & will update the original post when there is more info.

Seems that it doesn’t fix the bluetooth

I found this in the dmesg :

[ 3324.013612] Bluetooth: hci0: Opcode 0x0401 failed: -110
[ 3324.013622] Bluetooth: hci0: command 0x0401 tx timeout

[ 3798.051495] Bluetooth: hci0: unexpected event for opcode 0x0401

and for the bluetooth journalctl :

OK…I did a Google Search on: bluetoothd[993]: src/profile.c:ext_io_disconnected() Unable to get io data for Hands-Free Voice gateway: getpeername: Transport endpoint is not connected (107)

And got several hits…..Bummer that the downgrade did not fix your problem…It looks like it may be harder to track down. This stood out in the search: https://github.com/arkq/bluez-alsa/issues/339
