Preparing our project

We create a new Universal Windows Platform application project, based on the Sensor project described in chapter 2. This time, we call it SensorMqtt. We use the same hardware setup and sensor code developed earlier. In this chapter, we will focus on how to publish the information we've sampled on the internet, and how to receive it. We begin by adding a new NuGet package, the Waher.Networking.MQTT.UWP package. This package contains a simple MQTT client we can use to communicate using the MQTT protocol. We also add the Waher.Runtime.Settings package introduced in the previous chapter.


For.NET standard, .NET Core, or traditional .NET Framework projects, you can use the Waher.Networking.MQTTNuGet instead. UWP apps use different libraries and runtime binaries when it comes to communication and encryption. For this reason, it requires a somewhat modified version of the original library.

Selecting an MQTT broker

To use MQTT, you need to decide what MQTT broker you will use...
