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.

Messaging - commands and control

Any IoT device which is capable of receiving messages from the cloud makes a bidirectional command execution easy. The device can receive the message and process upon the instruction on the hardware side. Once the action is taken, an acknowledgement is sent to the cloud about the action completion. With the IoT Hub SDK for the device and the backend application, we can achieve this. We must follow the following steps:

How to do it...

In this section we will send a cloud-to-device message. Upon receiving it, the IoT device will perform an action:

  1. Send a cloud-to-device message from a cloud solution to an IoT device:
ServiceClient serviceClient;
serviceClient = ServiceClient.CreateFromConnectionString...
