arduino with BT code

Hello, I am a student of electricity engineering, in my last year. my final project contains some arduino controller working with BT modem bluesmirf silver. my project is to transmit a some signal named "modem" and search for another signal called any other name i will define. when the BT finds this other name in area it needs to turn on a buzzer. so no pairing is actually need to be made, only signal name reading. additional there need to be a button when pressed on he will change the signal name to another name i will define. thanks Shay
