ESP8266 Community Forum

I have a question concerning the ESP8266 module.
I am thinking about use it on my project but I don't know if it will be suitable for what I need to do.

Work with one is fine. But is it possible to have more than one module connected to one server (I will use a Raspberry Pi to send the messages), with each module having a specific address so that it is possible to control each ESP8266 individually (sending addressed messages over the internet)?

Thanks for the help.

I'm doing something similar. http://adityatannu.com/blog/post/2015/1 ... ories.html

Each esp connects to a different network and by pulling the C/s wire indepently the master can communicate to them seperatly.
