Problem with rfm_ethernet

[Salah]

I have been working to have done this project 
just I have a problem with the rfm Ethernet I have got the 433Mhz chip but when i start testing it on 
serial monitor the message only I have got " listening  to 433 " and after that it stop 
please if someone has an idea about it, because i have to demonstrate the project nearly.
Thank you

you need to have 2 devices communicating to each other otherwise there will not be any serial output about traffic. there are some very simple sketches out there (I referenced on in one of my posts) for testing connections.
