In this chapter, you will learn how to send data to an IoT server using the MQTT protocol with a LoRa wireless network. The ThingSpeak IoT platform enables clients to update and receive updates from channel feeds through the ThingSpeak MQTT broker. MQTT is a publish/subscribe communication protocol that uses TCP/IP sockets or WebSockets. MQTT over WebSockets can be secured with SSL. A client device connects to the MQTT broker and can publish to a channel or subscribe to updates from that channel.

The network you’ll build consists ...
