ESP8266 Community Forum

Hi all,

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.

Yes, you can use something like MQTT where you can publish messages on different topics. Each ESP8266 module can subscribe to one or more topics. esp8266/arduino already has support for MQTT. All you need is an MQTT broker running on a computer or Raspberry Pi.

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

Can the C/S pin not be used here?

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