Onos need to have shorter radio messages,to improve long range comunication.
So the new messages will be:

Standard part to all messages :

"[S_" 3 byte for the start of the message
2 bytes for the address of the node expressed in hex format max number is FF --> 255
1 byte for the type of msg expressed in ascii character
1 byte for the message id (a progressive number from ascii 0 to 9 to identify the message, first time will be 0 next 1 and so on)
"#_]" 3 byte for the end of the message

The message to change the value of a generic digital object node will be:

3 bytes with "[S_" for the start of the message
2 bytes for the address of the node expressed in hex format max number is FF --> 255
1 byte containing "d" for the type of msg , set digital object
2 bytes for the number of the object to change expressed in hexadecimal(for first object of the node it will be "0")
1 byte to tell arduino the value (0 or 1 ) to set the object
1 byte for the message id ,a progressive binary number from 0 to 255
3 bytes with "#]" to close the message
example: [S_01d001x#] to set the first object (00) of the node to 1, (x is the id value)
[S_01d000x_#] to set the first object (00) of the node to 0, (x is the id value)
