WiFi

• You can connect to WiFi using any application, such as : connmanctl or wpa_spplicant.

An example for connecting to WiFi using wpa_supplicant:

1. To bring a WiFi interface up, run the following :

$ ifconfig wlan0 up 

2. Install the wpa_supplicant package:

$ apt-get install wpasupplicant 

3. Edit network interfaces file :

At the bottom of the file, add the following lines to allow wlan as a network connection:

cat <<EOF > /etc/network/interfaces.d/wlan0
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. You can check it by running the command $ iwconfig . If it doesn't, repeat above steps or get help from an adult.

• For more information about using wpa_supplicant , you can refer to wpa_supplicant or wpa_supplicant.

Bluetooth

[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 :

[bluetooth]# paired-devices

Cellular Modem

The cellular modem is a more fully featured extension of which contains a cellular module with additional hardware interfaces and a SIM card slot.

You can connect your cellular modem to the mPCIe, and insert a SIM card.

• How to connect to the network:

  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

GUI On Debian

There is an option with the Debian image, up to the user, to work with a GUI like Weston, GNOME and etc.
For applying this option do the following steps:

First, connect your device to a screen using the working output (HDMI / uHDMI).

For working with Weston GUI:

1. Install the Weston package.

   sudo apt install weston

2. Set the XDG_RUNTIME_DIR env param.

   cat << 'EOF' > /etc/profile.d/weston.sh if test -z "$XDG_RUNTIME_DIR"; then export XDG_RUNTIME_DIR=/run/user/`id -u` if ! test -d "${XDG_RUNTIME_DIR}"; then # Make a directory for the output of the Weston GUI mkdir --parents "${XDG_RUNTIME_DIR}" chmod 0700 "${XDG_RUNTIME_DIR}" fi fi EOF

3. Restart the system

   reboot

4. Start Weston (must be run from the Dissplay Terminal)

   weston

For working with GNOME GUI on top of Xorg:

1. Install Xorg.

   $ sudo apt install xorg

2. Install your desired gnome.

   $ sudo apt install gnome-session

   NOTE: ‘gnome-session’ is an example of gnome that we can work with, you can replace the ‘session' with another GNOME extention.

3. Start your GNOME GUI.

   $ sudo systemctl start gdm

   • For logging in you need a user on your device to log into it. You can create one before step 3 by this command (replace the ‘username’ with name that you want) :

   $ sudo adduser username

   • You can jump between GUIs that you install (like gnome-session) by the setting button that locates in the down right corner of the home screen.
