hello

Bluetooth

Scanning BLE

Scanning BLE is from https://elinux.org/RPi_Bluetooth_LE

device testing

1. Check what devices you've got

   lsusb

2. Basic installation checks: The Pi 3's built-in Bluetooth adapter is called hci0. You can check it is operating correctly with the command:

   hciconfig

3. If you are on a laptop two(2) hci devices will show up, the first one is buggy

   hciconfig hci0 down

4. Now you can try scanning for BLE devices

   hcitool lescan

Python programs

1. do stuff

   sudo apt-get install python-pip

   sudo apt-get install libglib2.0-dev

   sudo pip install bluepy

   blescan

Setting an IPv6 address

following the lowpan 802.15.4 blog

• add apt-get install libnl-3-dev

Hi und danke erstmal,

bin jetzt soweit mit fast allen befehlen durch 

Code: [Auswählen]
pi@raspberrypi:~ $ ls -l /dev/ser*
lrwxrwxrwx 1 root root 7 Feb 28 23:59 /dev/serial0 -> ttyAMA0
lrwxrwxrwx 1 root root 5 Feb 28 23:59 /dev/serial1 -> ttyS0

das sieht schon mal gut aus, lt. deinem Howto
allerdings bekomme ich dennoch kein Device : 

Code: [Auswählen]
pi@raspberrypi:~ $ hcitool dev
Devices:
pi@raspberrypi:~ $ hcitool scan
Device is not available: No such device
pi@raspberrypi:~ $ 

glaub bin zu müde oder zu blind.
habt Ihr eine Idee ??

danke

pi@raspberrypi:~ $  systemctl status bluetooth

pi@raspberrypi:~ $ sudo bluetoothctl

pi@raspberrypi:~ $ dmesg | grep Blue
[   22.873317] Bluetooth: Core ver 2.22
[   22.873369] Bluetooth: HCI device and connection manager initialized

so alles was mit Bluetooth zu tun hat gelöscht und folgendes getan

Code: [Auswählen]
sudo apt-get install raspberrypi-sys-mods

sudo apt-get --reinstall install pi-bluetooth

sudo shutdown -r now


dann 

Code: [Auswählen]
sudo systemctl start hciuart.service
pi@raspberrypi:~ $ systemctl status hciuart.service
● hciuart.service - Configure Bluetooth Modems connected by UART
   Loaded: loaded (/lib/systemd/system/hciuart.service; disabled)

   CGroup: /system.slice/hciuart.service
           └─962 /usr/bin/hciattach /dev/serial1 bcm43xx 460800 noflow -



und siehe da!!!

Code: [Auswählen]
pi@raspberrypi:~ $ hcitool dev
Devices:
	hci0	B8:27:EB:90:BC:6D

es geht!!

danke an alle!
