Objectives

• Support GSM modems
• Support Ethernet featherwings
• Support Wifi in AP mode

This looks awesome @damz ! It looks to me in a quick read like the connection type is driven by the configuration settings.

One additional thought / improvement I was considering.

Do you think it's possible / would it make sense to have some sort of auto connection hierarchy that would remove the need for the configuration depending on what settings are configured / what hardware is available? The benefit of this is that for users building the Frog kit with a cellular modem, they wouldn't have to use Curl / a command line tool to change the network config.

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

@damz I am planning on taking this over. Was there any known outstanding work or issues when you left it?

[keenanjohnson]

Moving to a new PR so I can take this over: #39.

@damz if you have any memories of what the state of this was when you left it, that would be immensely helpful so I know where to start. Really appreciate it!
