Hello,

I have a project in which I have 4 arduino card.

The first 3 cards are equipped with an ESP8266 ESP01 module and their role is to send the information.

The 4 cards is responsible for receiving the information and performing the necessary processing and it's equipped with a TP LINK Wr802N module.

I want to know is there a way to make the distinction between the 3 information received (I want to identify the card that sent the information knowing that the 3 cards sends the information simultaneously).

Thanks

Include an id in the transmitted information?

Thanks for your answer.

No the transmitted information is just data there is no id.

Well can you change that?

Else, we need to know, how the data is transmitted.
