Is it possible to resend an FM radio for NDS like the one on each mobile phone (which is transmitted with the headphones?)
No, they need a radio receiver chip (which has negligible cost to include inside wifi/bluetooth ones)Just one thing to say : ( i am not a professional guy in "radio" ) , but a lot of phone ask for headphones if I want use the radio app ( the headphones is used as antenna , so it need only a software , no ? ).
