Bluetooth stops working on multiple pi's after some time, reset fails

[wtangofoxtrot]

Seeing this issue across my pi3/4s in the house, bluetooth stops working by itself and room-assistant is unable to reset it. The syslogs show the following message in a loop:

Only fix I've used so far is a cron task to reboot these pi's every night to keep them working.

@wtangofoxtrot I have the same issue until I restart my pi.

@mKeRix can you please look into this? Thanks

I have the same problem, too bad I use the room assistant to track cars in and out of the garage!

This issue still keeps happening across all my pi's, ive tried to setup a cronjob to reboot them every day but that is still not sufficient as it might start a few hours after that. rebooting is the only fix afaik

Looks like hci0 just disappears after some time on all my p3/4s (Not seeing this on my Pi0 though)

example when a pi stops working:

No new release in a yr so definitely not a stale issue, shooo bot !

[vistalba]

Same issue on a Pi3 and Pi4. Not happening on pi zero w 2.

[mk-au]

Seeing this too on a Pi Zero W with Bullseye 5.15 kernel. Bluetooth stops connecting after about 24 hours and can only be fixed with a reboot. Only recently started happening.

Still having this issues.

[marsp88]

Similar issue here. After a while it stops detecting and only a restarts helps.
But it seems related to hcitool:

Command failed: hcitool -i hci0 cc "xx:xx:xx:xx:xx" && hcitool -i hci0 rssi "xx:xx:xx:xx:xx:xx"
Can't create connection: Input/output error
Get connection info failed: No such file or directory
