Key FeaturesMake your connected devices less prone to attackers by understanding practical security mechanismsDive deep into one of IoT's extremely lightweight machines to enable connectivity protocol with some real-world examplesLearn to take advantage of the features included in MQTT for IoT and Machine-to-Machine communications with complete real-life examplesBook DescriptionThis 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 messagesWhat you will learnUnderstand how MQTTv3.1 and v3.1.1 works in detailInstall and secure a Mosquitto MQTT broker by following

Learn IoT programming using modem JavaScript on the ESP8266 and its more powerful successor, the ESP32. This book teaches you how to implement common connectivity features of IoT products using Wi-Fi, HTTP, WebSockets, MQTT, mDNS, and secure communications as well as how to work with common sensors and actuators over Digital, I2C, and SPI connections. You'll be introduced to graphics and building touch user interfaces for IoT applications with this new hardware generation that is powerful enough to handle color touch screens. Along the way, tips and techniques are given for using JavaScript to get the most from the memory and performance available on the latest IoT hardware. More importantly, you'll see how to apply JavaScript programming language to combine diverse technologies ― networking, user interfaces, sensors, actuators, and product logic ―into a reliable, maintainable application at the heart of an IoT product.IoT Development for ESP8266 and ESP32 with JavaScript introduces a new approach to IoT software development based on JavaScript and pairs it with a new generation of IoT hardware.What You'll LearnDevelop JavaScript applications for the ESP8266 and ESP32 microcontrollers using the Moddable SDKWrite modern JavaScript applications for microcontrollersWork with fundamental developer tools for ESP8266/ESP32 developmentGraphics and GUI development for IoT productsAdd asynchronous (non-blocking) network connections to embedded appsWho This Book Is ForPeople interested in getting started with JavaScript development on microcontrollers; JavaScript developers working on web or server-side applications; Embedded developers working with hardware
