Bluetooth keeps turning on on its own

Help
1

Idk what is causing this to happen. It doesn’t seem to be an issue with GNOME or KDE since the issue is happening on both.

If I turn off bluetooth, like with bluetoothctl power off or doing it through GNOME or KDE settings, it turns off. But then ~1min later it turns on again. I don’t know what is causing this. Also when bluetooth is on, pipewire and/or dbus has high CPU usage which makes the power usage very high on my laptop. This issue started happening in the past few weeks. It probably started after I updated NixOS, but I don’t know when exactly it started.

This is my config (the computer this is happening on is jinlon, I didn’t check if it’s happening on gaming-computer)

What are some things I should try to find out what is causing this?

The first thing would be to look at the logs: journalctl -b -u bluetooth -u dbus -u pipewire. Also, if it’s hardware-related, look at the kernel messages: sudo dmesg | grep -i blue.

journalctl -b -u bluetooth -u dbus -u pipewire

does not have any logs when bluetooth turns on by itself.
dmesg did not show anything either.

But I opened up the GNOME Logs app, and I found this:

 3:02:37 PM dockerd: e[33m2025-03-20 15:02:37.584 WARNING (MainThread) [bluetooth_auto_recovery.recover] Bluetooth adapter hci0 [48:51:C5:88:95:AE] successfully turned back ONe[0m

so I suspect Docker was turning on the Bluetooth! I stopped and removed the Docker container so I will see if the problem goes away.

I’m pretty sure that solved the problem. It was the Home Asistant Docker container btw. I probably installed it to test out home assistant and then forgot about it.
