Android app that reads and displays Bluetooth RSSI (signal strength) during pairing.

Remote control airplanes get lost in fields with tall grass. The RC Plane will be equipped with a class 1 (high power) bluetooth device. The android phone will try to pair to it but will not be able to until it gets very close by because it is class 2 (lower power) So I want a digital (raw decimal) and analog (bar graph) display of RSSI on the upper portion of the cellphone screen. This will help someone 'hone in' on the high power device. This will help the cell phone user get close enough to the device to actually pair to it. Once paired it must mount as a COMPORT so a few other parameters can be displayed on the remainder of the screen in a 'blueterm' like window. I found a small posting that claims RSSI is available during pairing here: [login to view URL]
