WiFi Interface

WiFi

The MConn display uses a Redpine RS9113 WiFi module and supports two operating modes:

AP Mode (Access Point) — The display broadcasts its own WiFi hotspot. Other devices connect to it. This is the default mode.
Station Mode (Client) — The display connects to an existing WiFi network as a client.

AP Mode (Access Point / Hotspot)

In AP Mode, the MConn Display broadcasts its own WiFi hotspot. Other devices such as phones, tablets, or laptops can connect to it directly. This is the default operating mode.

Switching to AP Mode

Step 1 — Set the SSID and Password for the hotspot

The AP Mode credentials are stored in /etc/wpa_supplicant.conf. Since the root filesystem is read-only, remount it as writable before editing:

mount -o remount,rw /
nano /etc/wpa_supplicant.conf

Edit the ssid and psk fields in the network block:

network={
        ssid="Your-Hotspot-Name"
        frequency=2412
        pairwise=CCMP
        group=CCMP
        key_mgmt=WPA-PSK
        psk="Your-Hotspot-Password"
        proto=WPA2
        mode=2
        priority=2
}

Save and exit (Ctrl+X, then Y, then Enter).

Step 2 — Switch to AP Mode and restart

onebox-set-mode ap && systemctl restart network-wireless.service

Step 3 — Verify the hotspot is active

wpa_cli -i wifi1 status
ifconfig wifi1

The ifconfig output should show the IP address 192.168.87.1. The hotspot should now be visible on nearby devices.

Station (Client) Mode

In Station (Client) Mode, the MConn Display connects to an existing WiFi network. This is useful when the display needs access to a local network or the internet.

Switching to Station (Client) Mode

Step 1 — Set the credentials for the network to connect to

The Station (Client) Mode credentials are stored in /etc/sta_settings.conf. Since the root filesystem is read-only, remount it as writable before editing:

mount -o remount,rw /
nano /etc/sta_settings.conf

Edit the ssid and psk fields in the network block to match the network you want to connect to:

network={
        ssid="Your-Network-Name"
        pairwise=CCMP TKIP
        group=CCMP TKIP
        key_mgmt=WPA-PSK
        psk="Your-Network-Password"
        proto=WPA2 WPA
        priority=1
        scan_ssid=1
}

Save and exit (Ctrl+X, then Y, then Enter).

Step 2 — Switch to Station (Client) Mode and restart

onebox-set-mode sta && systemctl restart network-wireless.service

Step 3 — Verify the connection

wpa_cli -i wifi0 status
ifconfig wifi0

The wpa_cli output should show wpa_state=COMPLETED and ifconfig should show an IP address assigned by your network’s router.
