Afternoon folks. I’ve recently been reading up on LoRa/LoRaWAN/TTN for a project and seem to be going about in circles a little bit. There is a piece of hardware I planned on looking at that contained a Microchip RN2483A on it. The datasheet says that it has a
On-Board LoRaWAN Protocol Stack.
I am looking to do some sensor comms in an open outdoor space with max distances of ~500m (with an eye towards 3km+ down the road). The transceiver module is paired with an ATmega for the sensor processing. In an ideal world (if I am understanding things properly), I have a bunch of these end nodes scattered about, a gateway to collect the data, and TTN is a sort of back end to access and massage the data. That seems somewhat clear to me. What I don’t understand is, if I have two of these pieces of hardware with the micro/transceivers on them, is it possible to do testing and dummy up some comms to do evaluation? Or do I need to grab a gateway (which was a cost I didn’t want to put out until I knew things would work) and tie it into TTN? And as a follow-on, if I don’t need the gateway, would I still be able to leverage TTN with just the two endpoint nodes?
