I have one more question. How can i receive a request from server on the clientmode esp?
For example i want to change the state of any output pin, how to send it to this esp from server?

- Sun Jul 31, 2016 9:52 am #51847 In the previous case, your ESP was used as a client to the server, in such mode, server can only send commands by making ESP doing polling on the server, asking the server "do you wish I do something ?".
This method isn't efficient and will be slow.

The real way to do that, is that ESP should become a server by it own, waiting for remote request from the other computer with PHP code doing acting as a client. For exemple, an HTTP request could be something like "http://<esp_ip_addr>/gpio/<gpio_number>/ON" and "http://<esp_ip_addr>/gpio/<gpio_number>/OFF".
