Using Raspberry Pi 3, Linux test 4.4.9-v7+ #884 SMP Fri May 6 17:28:59 BST 2016 armv7l GNU/Linux

root@raspberry:/home/user# hcitool scan
Device is not available: No such device

What can be the issue here?

I have updated to latest

#sudo rpi-update

I have installed rpi-bluetooth

#sudo apt-get install rpi-bluetooth

This can be seen from 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

EDIT:

This might also be interesting, why is not Bluetooth here?:

root@raspberry:/home/user# rfkill list
0: phy0: Wireless LAN
    Soft blocked: no
    Hard blocked: no

EDIT 2: I have tried to reinstall pi-bluetooth

I suspect that the last error has something to do with it: Job for hciuart.service failed. See 'systemctl status hciuart.service' and 'journalctl -xn' for details.

  • It shouldn't make a difference but what if you call hcitool with sudo? – rob May 08 '16 at 15:12
  • No difference, I have already runned sudo bash so I am in a root shell – www.jensolsson.se May 08 '16 at 17:55
  • Did you solve this issue? I wonder how you solved it – mozcelikors Oct 06 '17 at 14:30

    I see the same issue on my Pi 3 Model B V1.2, and I found that putting the exact same SD card in my Pi 3 B+ worked without issue. If you have another Pi 3, maybe try that out and see if it works? Others have reported this issue in the past, but software fixes worked for them, and keep failing for me. I can't attach to the BT module. https://github.com/raspberrypi/linux/issues/1314#issuecomment-190788662, https://stackoverflow.com/questions/44554255/bcm43xx-init-initialization-timed-out-with-buildroot-raspberry-pi-3-hciattach, https://archlinuxarm.org/forum/viewtopic.php?f=60&t=10770 – Will Haley Dec 13 '18 at 06:03

I had the same issue

pi@jarvis:~ $ hcitool dev
Devices:

with a inactive hciuart.service

pi@jarvis:~ $ systemctl status hciuart.service
● hciuart.service - Configure Bluetooth Modems connected by UART
   Loaded: loaded (/lib/systemd/system/hciuart.service; enabled)
   Active: inactive (dead)

After a

pi@jarvis:~ $ sudo systemctl start hciuart.service

I've got

pi@jarvis:~ $ systemctl status hciuart.service
● hciuart.service - Configure Bluetooth Modems connected by UART
   Loaded: loaded (/lib/systemd/system/hciuart.service; enabled)
   Active: active (running) since Sat 2017-05-20 17:42:40 CEST; 2s ago

and

pi@jarvis:~ $ hcitool dev
Devices:
    hci0    B8:27:EB:E5:7C:B0

Check your file /boot/config.txt for an entry like 

dtoverlay=pi3-disable-bt

and make sure this line is commented out by adding a # at the beginning of the line. If it is not commented out this line will disconnect the bluetooth from the UART and connect the UART with GPIO pins instead. Hope it works for you!

Do not use BerryBoot, and try sudo apt-get update and sudo apt-get upgrade. Or you can reinstall the newest raspbian from official site.
