[Bluetooth] No default controller available

So I'm trying to get the bluetooth of my laptop (Acer Aspire V5-131) to work, so far unsuccessfully.

I manually started the bluetooth service.

Yesterday after losing access to my EFI partition had to re-install Arch and on the first boot with a graphical interface I was able to make it work.
I had a controller and successfully connected my mouse. After rebooting, 'no controller available'.

I already tried blacklisting gsmi and didn't seem to work.
Any ideas?

Thank you very much!!

Re: [Bluetooth] No default controller available

Same problem here but with an intel network controller.
I've solved with: sudo pacman -S linux-firmware
