I've removed blueman so only "bluetooth" service is running:
systemctl list-unit-files|grep blue

bluetooth.service                          enabled         enabled
dbus-org.bluez.service                     alias           -
bluetooth.target                           static          -
bluetoothctl:

bluetoothctl

Agent registered
[bluetooth]# show
No default controller available
so no controller is detected.

I've installed linux-firware & I'm a member of group "bluetooth".

Any suggestions?.

Thanks
