Hi, there is known problem of the Ralink RT3290. You need to install this package: rtbth-dkms-git

But before installing keep sure, that you have installed the headers of your kernel. Check which kernel you are running:

uname -r

then for example

pamac install linux57-headers

then build the dkms:

pamac build rtbth-dkms-git

after rebooting it should work.

How to use it

# Init
sudo modprobe rtbth
sudo rfkill unblock bluetooth
hcitool dev # check

# Switch off
sudo rfkill block bluetooth

# Switch on
sudo rfkill unblock bluetooth

# Shutdown
sudo pkill -2 rtbt
sudo rmmod rtbth

Good sucess :wink:
