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.

Discovering the advanced functions of the ESP8266

Using the ESP8266's advanced features, you can expand the scope of your projects. This recipe will look at some of the available additional features and their possible applications. Some of the additional features include:

  • Wi-Fi connectivity

  • Real-time clock

  • Over the air update

  • Low power management

  • Working with files

Wi-Fi connectivity

The ESP8266 has a Radio Frequency (RF) transceiver with the following modules:

  • 2.4 GHz transmitter and receiver

  • Power management

  • Real-time clock

  • High-speed crystal oscillator and clock generator

  • Regulators and bias

The RF transceiver supports 14 channels within the 2.4 GHz band in accordance to the IEEE802.11bgn standard. The channels range from 2.412 to 2.484 GHz. The RF receiver employs the use of Automatic Gain Control (AGC) integrated RF filters and DC offset compensation to accommodate the different signal channels.

A high-power CMOS amplifier drives the antenna. This enables the RF transmitter to achieve an average...
