Diagnosing bluetooth issue

Sage · April 12, 2024, 1:16pm

Good day dear reader,
I have been having an issue with bluetooth. It works sometimes. But when it doesn’t no matter what I do it just don’t respond.

I have a new Lenovo LOQ laptop on which I have freshly installed Endeavour OS.

In the beginning everything was ok except battery drain issue. For which I used powertop and set all the options that was set to “Bad” to “Good”. I notice some improvement but not by lot. I am able to only get 1.5 hours of battery. Even though the advertised battery backup is at least 4 hours.

While this issue is still pending. My bluetooth has suddenly behaving erratically. It works sometimes, and when it does work, it only work for 10-20 minutes and then it automatically gets disconnected. In some cases although the bluetooth is on, apparently. but it is unable to find any devices and also no external device (cell phone) is able to find the pc. While sometimes it is able to find it but fails to connect to it. Same goes for the other way around.

I don’t know what could be wrong here. Since I have swept through dmesg, journalcl, etc and see some errors messages, But my untrained eyes can’t figure out what they are. I also saw few errors in systemctl status bluetooth unfortunately I didn’t save those and now I have so far failed to reproduce them.

Here is some info, that might be useful. ( let me know if you need any more info)

The issue is resolved (mostly), here is how:

/etc/bluetooth/main.conf

DiscoverableTimeout = 0
PairableTimeout = 0
ControllerMode = "bredr"

/etc/bluetooth/input.conf

IdleTimeout=0

When bluetooth headset is connected, go to audio settings and change its profile to:
HSP/HPF one.

I do sometimes get the random disconnection but not that often. The main issue is I think:

Unable to get Hands-Free Voice gateway SDP record: Host is down

If anybody knows how to restart the said host then that would save me from rebooting.

For this, I tried, but to no avail :

systemctl --user restart wireplumber.service
systemctl --user restart pulseaudio
systemctl --user restart pipewire-pulse.{service,socket}
systemctl --user restart pipewire.{service,socket}
systemctl restart bluetooth

Thank you.

should be all needed to restart BT connection handling…

“host is down” is mostlikely a powersaving issue.

You mentioning to use powertop, here keep in mind that you need to check what else is already in use:

https://endeavouros.com/#packages

We set power-profiles-daemon enabled by default, another power management tool used at the same time could cause issues.

In Case you are using AMD CPU it could be a good idea to have a look to exchange PPD with TLP:
https://wiki.archlinux.org/title/TLP
