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.

Message Queuing Telemetry Transport Protocol (MQTT)

MQTT targets device data collection. It is mainly used for telemetry, or remote monitoring purposes. MQTT collects data from many devices and transports that data to backend IoT services using publish and subscribe technique.

Getting started

Currently, IoT Hub offers two ways of implementing the MQTT protocol. The first option is to use the IoT Hub device SDK itself. This is suitable if you can easily write the code on the device side.

Secondly, you might face challenges in using IoT device SDK and writing the code on the device; especially if you have old devices in the fields. The solution is to use the MQTT protocol directly.

Let's try the option with IoT Hub device...
