Lately i had been dealing with an issue where my bluetooth would disable automatically upon login. I had done a lot of troubleshooting to realize that the issue was with me abruptly rebooting instead of rebooting via the gui.
Which would cause ~/.config/bluedevilglobalrc to look something like this:
[Adapters]
44:85:00:80:3C:BA_powered=false
Solution:
1. Comment out the line to look something like this:
[Adapters]
#44:85:00:80:3C:BA_powered=false
I have tested this and there does not seem to be any functionality issue whatsoever
2. Make the file read-only or immutable
- Change the file to look like this:
[Adapters]
44:85:00:80:3C:BA_powered=true
$ chattr +i ~/.config/bluedevilglobalrc

The issue does not seem to persist anymore, atleast for me, it’s been a while since anything weird happened with my bluetooth. If you are still facing issues maybe you can try the above, or report relevant bugs at bugs.kde.org for better support.
