This post summarizes an updated tutorial on how to configure the Dragino LoRa Shield device for the Australian/New Zealand (AU915) frequency using my fork of the MCCI Catena version of the Arduino-LMIC library. Contents Background Quickstart Arduino Environment Setup MCCI Arduino-LMIC Library Configuration Sample Dragino LoRa Shield Sketch Conclusion Background I recently wrote a post about Configuring a Dragino LoRa Shield for use on the AU915 frequency so that the device can be used legally…

This post outlines a tutorial and explanation of how to use the Paho MQTT JavaScript library to build a basic web application to subscribe to MQTT messages from a broker. The resultant source code is available from the following repository: js-mtt-websockets-demo. Please feel free to use it as a base in your project. The final web application is simple, yet functional. Contents Introduction The Eclipse Paho MQTT JavaScript Library MQTT Over Websockets Building an MQTT Web Application Creating…

Update: This tutorial is now considered out-of-date. I have written a new tutorial which uses a more recent version of the Arduino-LMIC library modified by MCCI which has much better support for the AU915 frequency. Please view the updated Dragino LoRa Shield Node Configuration for AU915 (Updated) post for more information.
