Wifi broadcast using ESP8266

[mril]

Hi,
I've been told that I can have a data communication between a bunch of ESP8266, what I want to do for the moment is to send from an esp device, an information to the ESP8266 devices around, can you please tell if it is possible to do it using AT commands, and how a broadcast mode works.
sorry for my bad english
tks for HELP

Hello,

If you want to send a message (the same message) to many ESPs, technically the most simple way would be to send a message to 192.168.4.255 at any port. This will work with the subnet mask 255.255.255.0.
The other stations will receive the message when they are listening to the same port and are connected to the same network.
This should work when using AT commands as well.

Okey and which AT command do I have to use for that ?
