Hello I want to make communication between several ESP8266 modules preferably over UDP. I would like 3 modules to have temperature sensors connected and send temperature values to another ESP, which will display these temperatures on a web page. What should the schematic of such a task look like...

Do you want to make a webserver on one? That's what I used to do, too, but I came to the conclusion that it didn't make sense. Eventually I made a collection point on BananaPi.

. Why does such a solution not make sense? What communication protocol did you use ?

Hi. I don't use it myself, but here's the first link from google:

Hello
I want to make communication between several ESP8266 modules preferably over UDP. I would like 3 modules to have temperature sensors connected and send temperature values to another ESP, which will display these temperatures on a web page. What should the schematic of such a task look like? On the internet I only found how to listen over UDP, but I don't know how to send something to another ESP over UDP.
I am programming in Arduino IDE.

Do you have a problem with Arduino? Ask question. Visit our forum Arduino.
