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.

Processing device-to-cloud messaging

Cloud-to-device messages are important for any IoT device, which are mainly focused on some feedback or maintenance of these IoT devices. We send cloud-to-device messages through a service-facing endpoint (/messages/devicebound). A device receives them through a device-specific endpoint (/devices/{deviceId}/messages/devicebound) and takes the appropriate action on the device side based on the logic developed for the device.

These communications make the device bidirectional; some examples of bi-directional commands could be to change the configuration for a device, these fields can be time interval the device sends the data, updating some local model, size information.
