KC868-H16 TCP PHP sample code

[jfementira]

see this guide about PHP tcp socket connection code:
https://www.php.net/manual/en/function.s...onnect.php

So it is just a string to send to the server/device?

Sample:  

PHP Code:

$message = 'RELAY-SET-255,1,0';
socket_write($socket, $message, strlen($message));
