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.

Functionalities of the ESP8266

The first thing we will tackle is the functionality of the ESP8266. We will look at the features and functions of the ESP8266, and learn about all the available GPIO pins and how we can use them to read and write digital signals.


The ESP8266 chip provides a self-contained, standalone Wi-Fi networking solution that allows you to host applications and to provide a Wi-Fi network that you can use to transfer data and instructions in your projects.

In normal use, the ESP8266 boots up directly from an external flash memory. It also has a cache that improves the performance of the system and reduces the amount of memory needed during operation.

The ESP8266 can also be used as a Wi-Fi adapter. In this case, the chip provides wireless Internet access to a microcontroller-based project through either the CPU AHB bridge or UART interface.

The on-board processing and storage capabilities of the ESP8266 enable easy integration with sensors and other devices via the...
