Overview of this book

The ESP8266 Wi-Fi Module is a self contained System on Chip (SOC) with an integrated TCP/IP protocol stack and can give any microcontroller access to your Wi-Fi network. It is capable of either hosting an application or offloading all Wi-Fi networking functions from another application processor. This book contains practical recipes that will help you master all ESP8266 functionalities. You will start by configuring and customizing the chip in line with your requirements. Then you will focus on core topics such as on-board processing, sensors, GPIOs, programming, networking, integration with external components, and so on. We will also teach you how to leverage Arduino using the ESP8266 and you'll learn about its libraries, file system, OTA updates, and so on. The book also provide recipes on web servers, testing, connecting with the cloud, and troubleshooting techniques. Programming aspects include MicroPython and how to leverage it to get started with the ESP8266. Towards the end, we will use these concepts and create an interesting project (IOT). By the end of the book, readers will be proficient enough to use the ESP8266 board efficiently.

Cloud machine to machine interaction

Interaction between two ESP8266 boards in remote locations is possible through cloud machine to machine communication. This recipe is going show you how to build a simple M2M project in the cloud with two ESP8266 boards. To achieve that, we will use MQTT.

MQTT is an M2M connectivity protocol that is used in the Internet of Things. It is a lightweight messaging transport that allows devices to publish or subscribe to different content online. Due to its lightweight nature, it uses very little bandwidth and resources while ensuring reliable data transmission between different clients.

The publish and subscribe pattern is what forms the basis for the MQTT protocol. The client that is sending a message is known as the publisher and the one that receives the message is called the subscriber. The publisher and subscriber do not interact directly with each other. There is a server known as the broker, which the publisher and subscriber connect to. The broker filters...
