Azure IoT Development Cookbook

By: Yatish Patil

Overview of this book

Microsoft’s end-to-end IoT platform is the most complete IoT offering, empowering enterprises to build and realize value from IoT solutions efficiently. It is important to develop robust and reliable solutions for your organization to leverage IoT services. This book focuses on how to start building custom solutions using the IoT hub or the preconfigured solution of Azure IoT suite. As a developer, you will be taught how to connect multiple devices to the Azure IoT hub, develop, manage the IoT hub service and integrate the hub with cloud. We will be covering REST APIs along with HTTP, MQTT and AMQP protocols. It also helps you learn Pre-Configured IoT Suite solution. Moving ahead we will be covering topics like:-Process device-to-cloud messages and cloud-to-device messages using .Net-Direct methods and device management-Query Language, Azure IoT SDK for .Net-Creating and managing, Securing IoT hub, IoT Suite and many more. We will be using windows 10 IoT core, Visual Studio, universal Windows platform. At the end, we will take you through IoT analytics and provide a demo of connecting real device with Azure IoT.

Device direct methods

Azure IoT Hub provides fully managed bidirectional communication between the IoT solution on the backend and the IoT devices in the fields. We will be considering detailed message communication in Chapter 3, IoT Hub Messaging and Commands.

When there is a need for an immediate communication result, a direct method best suits these scenarios. Let's take an example of a home automation system. One needs to control the AC temperature or turn the faucet showers on/off. It uses the HTTP protocol for method invocation.

How to do it...

The following steps will be taken to perform a direct method with an IoT device connected with IoT Hub:

  1. Invoke this method from the application:
public async Task<CloudToDeviceMethodResult...
