of the new service should include all the information needed to implement the new service. We recommend to
use PHP, so the new project could be developed faster reusing code created. The most useful PHP class is called
frame, which has been created to simplify the payload-answer process and it is located in:
your_callback_server_path/includes/class.Frame.php
“your_callback_server_path” has to be replaced with the path where the user has the callback server installed.
This is a complete description of all attributes and methods of the class frame:
Attributes
Name Description
private String data
Information received from the node.
private String type
Frame type decoded from the information sent from the node.
private String return
String to return to the node.
private String device_id
Device ID of the node.
private Array bytes
Information received from the node converted into bytes.
private Array bits
Array in which each previous byte is converted into bits.
private Array info
Array with the information decoded.
