ESP32 Client-Server Wi-Fi Communication Between Two Boards (ESP8266 Compatible)

ESP32 Client-Server Wi-Fi Communication Between Two Boards (ESP8266 Compatible)

ESP32 Schematics + Source Code ►
ESP8266 NodeMCU Schematics + Source Code ►

In this video you’ll learn how to setup an HTTP communication between two ESP32 boards to exchange data via Wi-Fi without the need to connect them to the internet. So, you don’t need a router.
Basically, you’ll learn how to send data from one board to the other using HTTP requests.
This project can be very useful if you need to setup a wireless communication between two boards or more and you don’t have a router nearby.

  1. Thanks for the video Rui. Quick questions:
    1) When ESP32 creates an AP, will the IP address be the same always?
    2) how many other ESP's can I connect to the Master ESP AP ?
    3) Will the Master ESP still be able to get connected to WiFi while it has it's own AP simultaneously?

  2. How to directly data transfer over wifi on 2 esp32 for make voice half duplex transmission, for example? Http requests is not accaptable variant?

  3. Hi. Two questions: 1) the IP needs to be get manually every boot? Since the client needs the IP of the server, can it be pre-set? 2) In this case the server sends data to the client. Can you show an example in which two clients send data to one server?

  4. Thanks for the great video! I have a question… I see the client requests data and the server replies with the three requested values, but is there a way to also enable the server to request data and the client replies with some values? I have a need to initiate requests from both sides.

  5. Hi, sorry if the question is stupid, I'm new to the field


    A white window with the name of the port to which the board is connected
    What is the name of this window and how do I get to it?
