Other Notes:
During my last login while Bluetooth did function as expected, I did perform an update. This was two or three days ago.

I did an apt update and installed a new deb -- firmware-atheros -- and that helped the situation. I have Debian repos enabled, not sure if firmware-atheros is in PureOS repos.

I just completed a bluetooth transfer of a photograph from my Pixel to the Librem 13 v3.

I'm experiencing a similar issue. Bluetooth will stop working sometimes after unlocking the session / resuming from a suspend. Restarting the bluetooth daemon does not resolve the problem.

It's also impossible to turn bluetooth off and on again using the Gnome UI.

Last time it happened I added the debugging option to the bluetooth service, but did not find any meaningful log after the next crash. Any advice as to what/where to look for would be appreciated.

I'm also using the firmware-atheros.
