Frequent Bluetooth Disconnects on Fedora 35

I just picked up a DIY edition with the AX210 module (no vPro). It seemed at first like it all “just worked” on Fedora 35, but I’ve found that when I use my Bluetooth headphones, they will frequently disconnect. But not in the way I’m used to. The laptop basically just stops sending audio to it, and shows it as disconnected, but my headphones don’t seem to “notice” for a minute, and once they finally do (I hear the beep boop that it uses to tell me that) it seems to quickly reconnect (boop beep) and then audio streaming resumes.

A few relevant package versions:

  • Linux kernel: 5.16.12-200.fc35.x86_64
  • bluez-5.63-1.fc35.x86_64
  • gnome-bluetooth-3.34.5-2.fc35.x86_64

journalctl output around this happening is a bit noisy, but likely the most relevant messages:

logs

When I fire up the bluetooth settings and connect my headphones:

then, a lot of messages like this:

And then, around when the sound stops:

Mar 09 21:49:34 framework-lappy wireplumber[2206]: 0x55e46ade0168: ioctl fail: Bad file descriptor

Mar 09 21:49:34 framework-lappy gsd-media-keys[2339]: Unable to get default sink

And this this starts repeating periodically (along with the Manager is NULL error above):

Mar 09 21:49:40 framework-lappy bluetoothd[922]: src/profile.c:record_cb() Unable to get Hands-Free Voice gateway SDP record: Host is down

Any advice would be greatly appreciated! These same headphones haven’t had issues like this working with my phone, macbook, windows desktop, etc, so it seems to be specific to either Fedora 35’s software, or the Framework hardware.

I think, I got the same problem, also on a DIY framework running Fedora 35. When using my bluetooth headset, watching for example youtube, it gets disconnected without the headset recognizing it and the video keeps running without sound output! Headset does not reconnect by its own, so I have to reconnect it manually by clicking disconnect and connect afterwards several times even.
Kind of annoying…

Good, I’m probably not crazy then! My next thing to try is to boot a Ubuntu live USB, to see if I can rule out the hardware.

I’ve noticed a similar issue on Linux when plugged to a bluetooth speaker and wonder if the problem is not related to this issue :

If it’s the case it’s probably not an issue with Framework (maybe an intel driver issue on the linux side as suggested at the end of the thread ?)
I do not have a windows install so I did not test if I was reproducing the issue on that OS.

I also see there’s an updated firmware package in Fedora today, which includes updates for this chip:

So far, so good, had a good 30 minutes watching YouTube videos w/ my bluetooth headphones with zero interruptions, after applying that OS update (which included updated bluetooth firmware, along with an updated Linux kernel).

Also did the update this morning and my JBL bluetooth headset is up and running without any issues until now. Great and thanks for the hint!
