allow-hotplug wlan0
iface wlan0 inet dhcp
wpa-conf /etc/wpa_supplicant/wpa_supplicant.conf
iface default inet dhcp
EOF

4. Create a configuration file with the relevant ssid:

cat <<EOF > /etc/wpa_supplicant/wpa_supplicant.conf
ctrl_interface=/run/wpa_supplicant
update_config=1
network={
    ssid="MYSSID"
    psk="passphrase" 
}
EOF

5. Make sure it works:

Restart your device and it should connect to the wireless network. If it doesn't, repeat above steps or get help from an adult.

3. Make your Bluetooth detectable by other devices:

[bluetooth]# discoverable on

4. If you want to connect to other devices:

• Start by scanning for other Bluetooth devices:

[bluetooth]# scan on

• Choose a MAC address and connect :

[bluetooth]# pair $MAC 

• You can check the pairing list between the devices by writing :

  $ mmcli -L

  3. Connect to your modem:

  $ mmcli --modem=/your/modem/location

  4. Enable the modem:

  $ mmcli --modem=/your/modem/location -e

  5. Scan for networks:

  $ mmcli --modem=/your/modem/location --3gpp-scan

  6. connect to 3gpp network:

  $ mmcli --modem=/your/modem/location --3gpp-register-in-operator=<network ID>

  7. Make sure the connection was created:

  $ mmcli --modem=/your/modem/location 

• For some cellular modules to be connected, please refer to Cellular Modules .
