hcitool tarama diyor Böyle bir cihaz yok

Raspberry Pi 3, Linux testi 4.4.9-v7 + # 884 SMP Cum 6 Mayıs 17:28:59 BST 2016 armv7l GNU / Linux

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

Burada sorun ne olabilir?

En son sürüme güncelledim

#sudo rpi-update

Rpi-bluetooth yükledim

#sudo apt-get install rpi-bluetooth

Bu dmesg'den görülebilir:

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

DÜZENLE:

Bu da ilginç olabilir, neden Bluetooth burada değil ?:

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

EDIT 2: Pi-bluetooth'u yeniden yüklemeyi denedim

Job for hciuart.service failed. See 'systemctl status hciuart.service' and 'journalctl -xn' for details.

Son hatanın bununla bir ilgisi olduğundan şüpheleniyorum: Job for hciuart.service başarısız oldu. Ayrıntılar için bkz. 'Systemctl status hciuart.service' ve 'journalctl -xn'.

Aynı sorunu yaşadım

Bir ile inaktif hciuart.service

Sonra

/Boot/config.txt dosyanıza benzer bir giriş olup olmadığını kontrol edin

dtoverlay=pi3-disable-bt 

ve satırın başına bir # ekleyerek bu satırın yorumlandığından emin olun. Yorum yapılmazsa, bu hat bluetooth'un UART ile olan bağlantısını kesecek ve bunun yerine UART'ı GPIO pinlerine bağlayacaktır. Umarım sizin için çalışır!

Kullanmayın BerryBootve deneyin sudo apt-get updateve sudo apt-get upgrade. Veya en yeni raspbianresmi siteden yeniden yükleyebilirsiniz .
