Socheara,
Your problem description is pretty vague. All you have given us is the structure for a struct that your code will send.

Before the transceiver sends a packet, it will need to do some setup tasks to wake up the receiver, find out if the receiver is ready to receive a packet, and communicate with the receiver about the format of the packet, just to name a few things. Then the transceiver has to send the packet, and receive some sort of confirmation that the receiver got the packet. In short, we need some more information.
