There is still some remaining work to here to investigate whether it's possible to automatically detect the network hardware and switch to the correct network settings.

The benefit of this is that for users building the Frog kit with a cellular modem, wouldn't have to use Curl / a command line tool to change the network config and existing Frogs could be updated with no config changes.

I am imagining for example the priority would be:

1. Ethernet
2. Wifi
3. Cellular

So the algorithm in my head would be:

• IF Ethernet hardware is installed
  • THEN set the config to ethernet
• ELSE IF Wifi configuration (SSID and password) are set
  • THEN set config to WIFI
• ELSE Then assume a cellular connection and set config to cellular
