Bluetooth works when it feels like it

General system Kernel & Hardware
#1

I’m trying to debug an issue where my Bluetooth mouse only works when it feels like it during a reboot or on a cold boot. I’m on a Thinkpad T495. My mouse might work, might not. What’s going on here?

I followed the EndeavourOS Bluetooth wiki page.
in /etc/bluetooth/main.conf , AutoEnable=true is enabled

bluetoothctl, rfkill, and lsmod

[fx9@fx9-thinkpad ~]$ sudo bluetoothctl
Agent registered
[bluetooth]# scan on
No default controller available

[fx9@fx9-thinkpad ~]$ rfkill list

Bluetooth service seems to be working

Could you post the link that you will find in the output of the following command:
inxi -FAZ --no-host | eos-sendlog

Did you try another kernel?

I have not yet tried another kernel but I will try the regular and lts.
EDIT: Tried the regular kernel, and has the same problem.

#4

The LTS kernel?

What is the output of systemctl status bluetooth.service when bluetooth is failing?

I would also suggest to look if there is a BIOS update for your device.

This is the output of bluetooth service when its failing

I would flash the latest BIOS and try the LTS kernel and if that doesn’t help wait for someone with more knowledge than me that can actually help you…Consider my effort to trying to keep your thread alive.

Thank you, I appreciate any help I can get :smiley:

So far LTS doesn’t look like it has this issue. I can’t seem to track it down but it does seem like a regression to me on the main kernel and zen kernel. I also can’t reliably produce the failing scenario.

Maybe with the next point release of kernel 5.18 all is well again. Those regressions happen some times, fortunately not too often.

#10

do you happen to also have windows installed and ever boot into it?

#11

No windows installed on this machine. I don’t ever want to run it.

#12

ok then its not windows deciding to claim the device

I had something similar happen because i had to use my windows usb drive to flash firmware onto one of my mobo sensor chips. After leaving windows the BT wouldnt work at times because Windows still had the device claimed and i had to boot back in, disable fastboot,etc. and THEN shut down to release it x|
