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

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.

You can find the complete project details on my blog!

How do this guy know what I'm doing 😳 Everytime I struggled & finish a project he publish exactly same as a tutorial. Last week only I needed it hardly & finished it at last. Now you made an easier tutorial.

THIS IS EXCELLENT!!! So many Tuts require a router network. I can figure it out, but it would be nice to see how you can "CONNECT" and use a browser to collect this data from say a laptop, or Android phone. Very helpful info here!! Great work!

Great example Rui, really useful I'd really like to see the same communication (print data) via Bluetooth for low power applications.

one of the best tutorial in esp32 in the youtube i saw, very well represented

[Hasan...]

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?

Pretty neat. I see you make three separate calls in yr asynchronous website, for temp, humidity and pressure. That makes it simple and very clear, but ofcourse also possible to make it with just one call

Hi Rui,
i am not trying to flatter you by any means, your tutorials are THE BEST in there respective topic. About the topic at hand, lets assume that i live in a community without internet connectivity, can ESP32 Server such that you demonstrated act as an AP to control something like 8 channel relay?

video simple, , complite, informatife, and something new

[benoitmbayo]

Great Video Rui, just what is the maximum range between the two boards?

[ATS]

Thank you for your Camera Project you are doing incredible stuff

[phil]

Thanks.
For the client any reason you choose ESP8266HTTPClient and not asynchroneous?
Are you aware that going to your website, makes high cpu usages?

[tonysicily]

Perfect, just what I needed, thank you Mr Santos.

[barajr]

Great video, but I have a question...can ESP32 communicate with 2 methods at once?
for example like ESP 1 - ESP 2 with ESP-NOW, then ESP 2 - PLC with wifi communication...

[anibalvilelarj]

Excelente artigo ! Vou usar como ponto de partida em um projeto meu. Muito obrigado, Rui !

[hervemarie]

Many tips in this project, excellent ! Thanks a lot !

[rgmtb]

Great project! I was looking for something like this to create a simple remote control for my camera slider project 👍 Thank you

[trego]

Thanks, Great job always The Source code with all comments is very helpful

[vino]

great. Master advice for e-money projects

i've been trying to make the same project but with using MPU 6050 sensor but i keep fail. can you please do a tutorial for this sensor too? I fail to do the String line and using the MPU 6050 library from what i think it does not support String or i do not know how to do it. this is an amazing project! thank you soo much!
