Bluetooth communications with C# 
I want to write 2 programs with C# one work on PC, the other work on a windows mobile phone.

So I want the PC program to send a signal via Bluetooth ( 1 byte maybe) to the windows mobile phone. and the mobile program (which work on background) handles and accepts this byte without the need of pairing.

how to code this?

please I need any kind of help.
