I guess you want to change rules when connecting to BT device on a distance, but otherwise you could buy NFC tag and using NFC tag bulider to make an NFC tag which can pair your BT device to your N9. Use the tag id to change rules. I've made it with my headset BH-111 and now it connects and starts the musicplayer (although I have to start playing the music with an extra click on the playlist, haven't yet figured out how to start music automatically with NFC rule)
