A pair of sample plug-and-play Arduino Uno R3 & Seeeduino V4.2 clients for my LoRa field gateway projects (see my profile for these).
The Arduino Uno R3 and Seeeduino V4.2 clients have been tested with 433MHz, 868MHz and 915MHz shields.
The design goal was a to use a couple of readily available 5V (Seeeduino can run 3v3 or 5v) devices to provide a simple demo sketch that students could use as a basis for their projects.
In future iterations I'm planning to improve the power consumption, implement basic OTA provisioning, sign the message payloads, encrypt the messages and support in field configuration.
Download the code, modify the configuration then build and deploy to device.
