MQTT Essentials - A Lightweight IoT Protocol: The preferred IoT publish-subscribe lightweight messaging protocol

by Gaston C. Hillar

This step-by-step guide will help you gain a deep understanding of the lightweight MQTT protocol. We'll begin with the specific vocabulary of MQTT and its working modes, followed by installing a Mosquitto MQTT broker. Then, you will use best practices to secure the MQTT Mosquitto broker to ensure that only authorized clients are able to publish and receive messages. Once you have secured the broker with the appropriate configuration, you will develop a solution that controls a drone with Python. Further on, you will use Python on a Raspberry Pi 3 board to process commands and Python on Intel Boards (Joule, Edison and Galileo). You will then connect to the MQTT broker, subscribe to topics, send messages, and receive messages in Python. You will also develop a solution that interacts with sensors in Java by working with MQTT messages. Moving forward, you will work with an asynchronous API with callbacks to make the sensors interact with MQTT messages. Following the same process, you will develop an iOS app with Swift 3, build a website that uses WebSockets to connect to the MQTT broker, and control home automation devices with HTML5, JavaScript code, Node.js and MQTT messages Gaston C.

Walks through how to run MQTT in no more than 5 different programming languages. Oddly enough so is not C or C++ really used at all. My experience when working as an IoT engineer is that C is by far the most frequently used language that runs on the sensor side.

Will as intended provide basic understanding of how MQTT is designed and used. Good read before building your first own system based on MQTT. It is nice that security is discussed throughout the book. Each chapter is ended with a little quiz which is a nice bonus.

I read the real book made from dead trees and it was published by Packt. I personally have issues with the current format and typesetting that this publisher is using in their books at the moment. The text is stretched out over quiet a wide page with 100 or so characters on each line. These long lines makes it harder than it should be to read their books since the eye have to wander a lot back and forth while reading.

All in all a good little book would have gotten four stars if it wasn't for the poor typesetting.

Well, this is a rather short book with I think lots of repetition especially how to set up the SSL part of MQTT. I understand this is essential, but still describing it once would have been enough for me.
