Su una nuova installazione di Raspbian Stretch, eseguo l'accesso e con il primo comando di systemctl status bluetooth
ottengo:
$ systemctl status bluetooth
● bluetooth.service - Bluetooth service

Di conseguenza, bluetoothctl
non rileva alcun dispositivo.
Questo non è successo con Raspbian Jessie. Qualche suggerimento su come risolverlo?
