How to Make Two ESP8266 Talk
In this project you’re going to make two ESP8266 talk with each other.
How it works? You’re going to set one ESP as an Access Point (Server) and another ESP as a Station (Client). Then they’ll establish a wireless communication and the Client sends a message to the Server saying “Hello World!”.
Before continue reading this project, please complete the following tutorials:
If you like the ESP and you want to do more projects you can read my eBook Home Automation using ESP8266 here. Let’s get started!
Here’s the hardware that you need to complete this project:
Schematics (3.3V FTDI Programmer)
The schematics for this project are very straight forward. You only need to establish a serial communication between your FTDI programmer and your ESP8266 to upload some code. (Repeat the schematics below for the Client and Server)
I recommend using the ESPlorer program created by 4refr0nt to create and save Lua files into your ESP8266.
Follow these instructions to download and install ESPlorer:
- Click here to download ESPlorer
- Unzip that folder
- Go to the main folder
- Run ESPlorer.jar. It’s a JAVA program, so you need JAVA installed on your computer
- Open the ESPlorer
