LoRaWAN stands for Long Range Wide Area Network. It’s a standard for wireless communication that allows IoT devices to communicate over large distance with minimal battery usage. At the time of writing this article I found that information about LoRa was rather sparse or overly complicated. Since it took me some time to really figure out what LoRa is and how it works, I decided to create this post and try to explain LoRaWAN in a technical but simply understandable way.
When testing or experimenting with LoRa, a test device that can send/receive LoRa packets on demand is a real value It allows you to test the network functionality and coverage. The Adeunis RF LoRaWAN Demonstrator is such test device. It can send and receive LoRa packets, has a built-in accelerometer and GPS and rechargeable battery. THis post explains how to configure the LoRaWAN demonstrator and add it to a network server.
The Microchip RN2483 is a LoRa class A module widely available. In a normal, end-user scenario, LoRa endpoints (or devices/sensors) come with preconfigured parameters but before the module can be used, it needs to be configured with those parameters to use it in the LoRa network. What parameters to configure depends on the type of activation. For this post, I’ve been using the RN2483 based PICtail test-board.
