By: Peter Waher

Overview of this book

The Internet of Things (IoT) is the fastest growing technology market. Industries are embracing IoT technologies to improve operational expenses, product life, and people's well-being. Mastering Internet of Things starts by presenting IoT fundamentals and the smart city. You will learn the important technologies and protocols that are used for the Internet of Things, their features, corresponding security implications, and practical examples on how to use them. This book focuses on creating applications and services for the Internet of Things. Further, you will learn to create applications and services for the Internet of Things. You will be discover various interesting projects and understand how to publish sensor data, control devices, and react to asynchronous events using the XMPP protocol. The book also introduces chat, to interact with your devices. You will learn how to automate your tasks by using Internet of Things Service Platforms as the base for an application. You will understand the subject of privacy, requirements they should be familiar with, and how to avoid violating any of the important new regulations being introduced.

Adding CoAP to our devices

We are now ready to implement CoAP in our projects. To do this, we create two new projects, which we will call SensorCoap and ActuatorCoap, copying the corresponding code from the Sensor and Actuator projects. If we wish to retain HTTP functionality, we can copy the code from the SensorHttp and ActuatorHttp projects instead. Our devices can support multiple protocols. We use the same hardware as we used in previous chapters. We add the Waher.Networking.CoAP.UWP NuGet package to both projects.


For .NET standard, .NET Core, or traditional .NET Framework projects, you can use the Waher.Networking.CoAP NuGet instead. Universal Windows Platform apps use different libraries and runtime binaries when it comes to accessing network adaptors. For this reason, it requires a somewhat modified version of the original library.

We must also make sure to initialize the runtime inventory of classes with a reference to the CoAP library assembly, in the beginning of the application...
