I'm positing this in the hopes that some kind soul could help me with and example of The following ;
A single server(esp8266) sending data (perhaps a string) to selected or multiple esp8266's and as they receive the data just to acknowledge back.
I am using the arduino iDE and have already checked out the other examples.
I had done this previously with NRF modules but I can't seem to find a clear example of this specific setup. Is it possible ?
I would really appreciate an example just to get me started.
Thank you
Den
