Best way to transmit data between two ESP8266-12 modules: UDP or TCP for sensors?

Welcome,

First of all, I would like to inform that I am a person just starting my adventure with ESP8266-12 module.
So, I'm planning to create a smart lighting system for a corridor, if someone enters the room, the first sensor detects movement - the first lamp will light up, when they reach the second one, the next sensor detects movement - the first one must go out and the second one will light up.
The whole system is to consist of two ESP modules and a motion sensor and relay connected to each.
What is the easiest way to program the modules to transmit data between them? Should it be via UDP? TCP?
Please help

Hello,
I had the same dilemma recently, I even asked a few posts below.
Today I'm a bit wiser now. The easiest way to communicate is via UDP. I decided to use the Arduino IDE, and although I had no previous experience with it I quickly got to grips with it.
There is one very good example of a UDP server, unfortunately I don't know if I can paste it here, but it's easy to find on google.
Regards

Thank you for your help, can you send me this example by email: przemo.dud(_at_)gmail.com

In Basic ESP it will be like this:

"Transmitter"



"Receiver:"

In my project all the modules have to transmit data between each other, it seems to me that one cannot be the transmitter and the other the receiver but one and the other must be the transmitter and the receiver. I have tested one example of UDP communication but I can only send text messages from one to the other, I can't find anywhere an example of how to e.g. send data from one module so that an LED lights up on the other. Please help

each ESP has a unique IDChip number. by this number you can attach or transmit data sequentially. It's a very simple algorithm.

And how can this chipID be checked/calculated? Is it written in the module documentation somewhere? Or is it simply a GPIO?

In Basic this is the command - id()
In LUA it is - node.chipid()
In C it will be ESP.getChipId()

In C will be the most writing, personally I prefer to write in LUA, or Basic. Although because of the ready-made libraries I use Arduino. I have to admit that I don't like this environment very much, and the plugin for ESP doesn't work for me in Atmel Studio.

And could someone give me an example of such an algorithm?

Show a diagram of what you have done, only then can you put together a program. Write in which language you want to write it, from my side I can help in C, Basic, LUA
