Hello! I'd like to keep a log of Bluetooth-devices appearing within "earshot" of my computer at home. I don't need to "pair" with them or do anything else actively -- just log the facts like these: 2012-09-11 11:47:50 00:11:22:33:44:55 appeared 2012-09-11 11:47:53 00:11:22:33:44:55 disappeared Where would I start? Thanks! Yours, -mi
