Hands-On Edge Analytics with Azure IoT

Creating our gateway (ESP32 LoRa)

For our gateway, we will use an ESP32 with LoRa. There are many of these types of boards in the market. They should all pretty much work the same. We will also use a built-in MQTT library to communicate with our MQTT broker.
