ESP8266 Internet of Things Cookbook

By: Marco Schwartz

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.

Programming your ESP8266 OTA

This recipe is going to demonstrate how to upload a sketch to an ESP8266 board over the air. We will upload a simple LED blinking program onto our ESP8266 board using OTA and implement some OTA routines to ensure safety during the upload.

Getting ready

In this recipe, we will need the following components:

Start by mounting the LED onto the breadboard. Connect one end of the 220 Ω resistor to the positive leg of the LED (the positive leg of an LED is usually the taller one of the two legs). Connect the other end of the resistor to pin 5 of the ESP8266 board. Then use a jumper wire to connect the negative leg of the LED to the GND pin of the ESP8266.

The setup is shown in the following diagram:

How to do it…

The first thing you need to do is set up your Arduino IDE for OTA updates. You will require the following things:

  • Python...
