Hey I’m a nixos kde user. I’ll share a snippet from my config related to BT which works insanely well with my HP laptop. Maybe that will help you
hardware = {
bluetooth.enable = true; # enables support for Bluetooth
bluetooth.powerOnBoot = true; # powers up the default Bluetooth controller on boot
};
### PipeWire doesn't need any additional config to work with BT
security.rtkit.enable = true;
services.pipewire = {
enable = true;
alsa.enable = true;
alsa.support32Bit = true;
pulse.enable = true;
wireplumber.enable = true;
};
Do you have the above code in your config? Have you got both Cinnamon and KDE installed?
This article was very helpful for me btw, maybe give it a shot
You really don’t have to install any bluetooth gui 'cause plasma already comes with built in one AFAIK.
If this doesn’t help, can you send the output of rfkill command?
[wynz@nixos-hp:~]$ rfkill
ID TYPE DEVICE SOFT HARD
1 wlan phy0 unblocked unblocked
2 bluetooth hci0 blocked unblocked
You might as well check system logs sudo journalctl -xb -u bluetooth.service
