@hek Hmm, what do you mean? That I build the Ethernet Gateway, and when I want to Serial fw, I compile it with SOFTSPI so I don't need to change pin locations?

Hello,

I'm about to make my first gateway and since I want the flexibility to switch controller, since I'm note sure if I want to run Indigo or OpenHAB, I thought of building a gateway that has the Ethernet module installed on the board. Then if I want to use it as a serial gateway for Indigo I can just re-flash the Arduino with the Serial Gateway firmware instead, and if I want to use MQTT or Ethernet - I'll just re-flash with those firmwares.

Now since the radio needs to be soldered differently on the Ethernet/MQTT gateway, is it sufficient to just change the pin locations in the Serial firmware? In other words I'll just change the following line:

MyGateway gw(DEFAULT_CE_PIN, DEFAULT_CS_PIN, INCLUSION_MODE_TIME, INCLUSION_MODE_PIN,  6, 5, 4);

To:

MyGateway gw(5, 6, INCLUSION_MODE_TIME, INCLUSION_MODE_PIN);

Is that correct? I'm not sure what the 6, 5, 4 pins are for though?

Also: Is it possible to hook up the MQTT gateway into the router instead, and still let the controller interact with it?

@mountainman Is there any instructions on how to wire/setup the hardware to work with your code?
