I have lost my Bluetooth headset somewhere in my home office. Silly I know, but with wall-to-wall stuff (wiring, books, equipment, and just plain junk), it has simply disappeared. It is a 'Plantronics Voyager Pro +' and is still operating. I narrowed down the search to my office, by noting how long it took to 'Connect' to the headset with my iPhone 4. My question is... has anyone seem an iOS or OS X app for measuring Bluetooth signal strength? Pleanty available for WiFi, but I can't find one for Bluetooth. With such software I might be able to zero in on the lost headset.
