CC2530: CC2530 writing RF code

Part Number:CC2530

Hi Ti 

I have two CC2530 development kit and I write  a simple  RF code to transmit  numbers from ( 0 to 254 ) from one kit to another and show them using UART0 .

now i want to use each kit as transmitter and receiver.

this mean that i want to send data from     kit 1   to kit 2    and then transmit data from   kit 2    to    kit 1   how can i do this ?

how can i adjust the receive time and transmit time for Two kits  So that there is no overlap to the data?

this is the transmitter code
