Bluetooth Mate Silver automatic pairing - Problem!


I'm developing this interface: that uses LilyPad Arduino with Bluetooth Mate Silver.

I'm having a big trouble trying to make its pairing automatic on MacOSx.
Everytime I turn Lilypad on, i have to paire it through the System Preferences.

This is a problem since - being a malleable interface - it is possible (inspite of unlikely) that Lilypad turns on/off quickly. By doing so, I completly loose bluetooth's signal, and have to do de whole protocol all over again.

Is it possible to configure it to paire automatically? Would this solve this issue I've pointed?

Thank you!
