Bluetooth Viewer

This app is for programmers, to debug the communication protocol between bluetooth devices and Android. The app simply shows the raw data coming from a bluetooth devices as ASCII text. You can also send data to a device, as ASCII text. I plan to add showing binary data in canonical hex+ASCII format, much like the hexdump -C command in UNIX.
