this can be solved by installing bluez & bluez-utils:

sudo pacman -S bluez bluez-utils

Nice. We only really document Debian setup at the moment.
We can't ofc keep track of every linux distro - but hopefully it's straightforward enough to set up on the major distros.
I'll add a section to the wiki with this ^ info - cheers.
