This project is now live on github.com, sample Arduino with Dragino LoRa Shield for Arduino, MakerFabs Maduino, Dragino LoRa Mini Dev, M2M Low power Node and Netduino with Elecrow LoRa RFM95 Shield clients uploaded in the next couple of days.
While building this AdaFruit.IO LoRa field gateway, and sample clients I revisited my RFM9XLoRa-Net library a couple of times adding functionality and renaming constants to make it more consistent. I made many of the default values public so they could be used in the field gateway config file.
The bare minimum configuration is
So far battery life and wireless communications range for the Arduino clients is looking pretty good.
