Bluetooth Toggling off immediately after trying to turn it on

Hey there, very new to linux

I’m on Fedora 42 and can’t turn my bluetooth on, see this gif:

My Laptop: **HP ZBook Ultra G1a**

Some things I tried but didn’t help:

sudo systemctl disable bluetooth && sleep 30 && sudo systemctl enable --now bluetooth

sudo rmmod btusb

sudo modprobe btusb

Some outputs:

systemctl status bluetooth

this command shows that something is down, not sure what it means though :smiley:

Let me know if you need any other info :slight_smile:

For some reason it suddenly works.

I don’t think / remember doing anything. I suddenly noticed that the “Blueetooth Menu” was blue and I can turn it off and on.

Not sure if any update happened to the system in the background I at least don’t remember installing it.

But I’m quite happy :smiley:

BlueTooth is often active at the UEFI/BIOS level to support BT keyboards, mice, etc. There can be conflicts with the linux driver, but often resolved with a power-off cycle.

Intersting. I for sure restarted a already before a few times, but it’s possible that I enver fully powered off for a few seconds. Anyay, happy to report, that it’s still working :smiley:
