Scanning BLE
Scanning BLE is from https://elinux.org/RPi_Bluetooth_LE
device testing
- Check what devices you've got
- lsusb
- 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
- If you are on a laptop two(2) hci devices will show up, the first one is buggy
- hciconfig hci0 down
- Now you can try scanning for BLE devices
- hcitool lescan
Python programs
- 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 ● bluetooth.service - Bluetooth service Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled) Active: active (running) since Do 2017-03-09 22:05:23 CET; 22s ago Docs: man:bluetoothd(8) Main PID: 794 (bluetoothd) Status: "Running" CGroup: /system.slice/bluetooth.service └─794 /usr/lib/bluetooth/bluetoothd pi@raspberrypi:~ $ sudo service bluetooth status ● bluetooth.service - Bluetooth service Loaded: loaded (/lib/systemd/system/bluetooth.service; enabled) Active: active (running) since Do 2017-03-09 22:05:23 CET; 27s ago Docs: man:bluetoothd(8) Main PID: 794 (bluetoothd) Status: "Running" CGroup: /system.slice/bluetooth.service └─794 /usr/lib/bluetooth/bluetoothd pi@raspberrypi:~ $ sudo hciconfig dev Can't get device info: No such device pi@raspberrypi:~ $ sudo bluetoothctl [bluetooth]# agent on Agent registered [bluetooth]# default-agent Default agent request successful [bluetooth]# scan on No default controller available [bluetooth]# exit Agent unregistered pi@raspberrypi:~ $ dmesg | grep Blue [ 22.873317] Bluetooth: Core ver 2.22 [ 22.873369] Bluetooth: HCI device and connection manager initialized [ 22.873381] Bluetooth: HCI socket layer initialized [ 22.873389] Bluetooth: L2CAP socket layer initialized [ 22.873408] Bluetooth: SCO socket layer initialized [ 103.040851] Bluetooth: BNEP (Ethernet Emulation) ver 1.3 [ 103.040860] Bluetooth: BNEP filters: protocol multicast [ 103.040871] Bluetooth: BNEP socket layer 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) Active: active (running) since Fr 2017-03-10 00:17:11 CET; 5s ago Process: 951 ExecStart=/usr/bin/btuart (code=exited, status=0/SUCCESS) Main PID: 962 (hciattach) 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!
