[Solved] Bluetooth doesnt work

since yesterday i cant use bluetooth in my laptop.
in kde environment it says there is no adapter available.

'rfkill list' says:         

0: phy0: Wireless LAN
        Soft blocked: no
        Hard blocked: no
1: hci0: Bluetooth
        Soft blocked: no
        Hard blocked: no

'dmesg | bluetooth' says:
bluetooth = on

'sudo hciconfig -a hci0 up pscan iscan' returns:
Can't init device hci0: Connection timed out (110)

I was able to connect my bluetooth headset 2 days ago, yesterday it stopped working with some diferent errors, today it is like this.
I update the system daily.
I have lts installed, but it is not listed in grub, i dont know how to use it to test with older kernel.

Add another entry to grub for -lts

Moving to NC...

Re: [Solved] Bluetooth doesnt work

Booting on the lts kernel and powering the adapter on solved the issue. Seems like a kernel problem. Thanks.

I figured out sometime ago I made a mess in my boot entries, I think i have more than one grub/arch entries on my efi, and cant figure out whats the correct and how i can delete the other safely.

I would like to have only one entry: /boot/efi/EFI/GRUB/

But when i do: "sudo grub-mkconfig -o /boot/efi/EFI/GRUB/grub.cfg", it says: "/usr/bin/grub-mkconfig: linha 237: /boot/efi/EFI/GRUB/grub.cfg.new: Arquivo ou diretório não encontrado" (no file found)

Re: [Solved] Bluetooth doesnt work

That's a separate issue. Open a new thread with details of your partitions, grub config and the error message in English:
