Bluetooth not detecting nearby devices

In my new arch install I am having trouble setting up my bluetooth
No devices are being shown in blueman/bluetoothctl

I have checked no device is blocked with rfkill
Also on my previous install everything used to work fine
but I think the bluetooth status is a little differet

I have tried restarting the service over and over even rebooting my pc
Also I am not on dual boot and use pipewire(but I guess device discoverability won't depend on it)

Re: Bluetooth not detecting nearby devices

You might be a victim of poor timing.  https://bbs.archlinux.org/viewtopic.php?id=300382

You might try a different kernel to check.  Or wait until the changes mentioned in that thread make their way into the Arch mainline kernel and try it again.

Re: Bluetooth not detecting nearby devices

Can confirm this is fixed in linux 6.11.4.arch2-1.
