Usando Raspberry Pi 3, prueba de Linux 4.4.9-v7 + # 884 SMP viernes 6 de mayo 17:28:59 BST 2016 armv7l GNU / Linux
root@raspberry:/home/user# hcitool scan
Device is not available: No such device
¿Cuál puede ser el problema aquí?
He actualizado a lo último
#sudo rpi-update
He instalado rpi-bluetooth
#sudo apt-get install rpi-bluetooth
Esto se puede ver en dmesg:
root@raspberry:/home/user# dmesg | grep Blue
[ 43.442353] Bluetooth: Core ver 2.21
[ 43.442453] Bluetooth: HCI device and connection manager initialized
[ 43.442477] Bluetooth: HCI socket layer initialized
[ 43.442494] Bluetooth: L2CAP socket layer initialized
[ 43.442528] Bluetooth: SCO socket layer initialized
[ 73.520196] Bluetooth: BNEP (Ethernet Emulation) ver 1.3
[ 73.520215] Bluetooth: BNEP filters: protocol multicast
[ 73.520238] Bluetooth: BNEP socket layer initialized
EDITAR:
Esto también puede ser interesante, ¿por qué no está Bluetooth aquí ?:
root@raspberry:/home/user# rfkill list
0: phy0: Wireless LAN
Soft blocked: no
Hard blocked: no
EDIT 2: he intentado reinstalar pi-bluetooth

Sospecho que el último error tiene algo que ver con eso: el trabajo para hciuart.service falló. Consulte 'systemctl status hciuart.service' y 'journalctl -xn' para más detalles.

Verifique su archivo /boot/config.txt para una entrada como
y asegúrese de comentar esta línea agregando un # al comienzo de la línea. Si no se comenta, esta línea desconectará el bluetooth del UART y en su lugar conectará el UART con los pines GPIO. ¡Espero que funcione para ti!
