bluetooth connection

i have been trying to connect my phone to my mbp but i can't get it to work. first i went into setup assistant. it discovered my phone then every time i get to the stage where the mbp sends a password to the phone it always say can't communicate or somthing along those lines.

I also tried it in reverse. i made sure the mbp was discoverable then i told my phone to look for devices but it didn't find the mbp.

if anyone has any tips on how to get my phone hooked up using bluetoothe please let me know

thanks
