Your English isnt too clear but if they are RF modules, you should be able to put data on the TX and receive it on the RX pin. plain and simple. I was able to transmit audible sound from a 555 timer in astable mode through a homemade FM transmitter and it worked like charm. you might not be able to pump that much data through the link though. Maybe a 1-2Mbits/s
