I've heard some people mention using bluetooth to communicate with microcontrollers as replacement for a serial or USB & FTDI. Recently some small bluetooth serial modules have become available from large electronics retailers and smaller ones that operate on large internet auction websites. They can be purchased now for just a few bucks. The module has all the bluetooth components integrated and takes 3 volt TTL level RS232 signals. It comes in a surface mountable pcb package, however…

Screen shots after some sporadic work. Accel and TX calibration is working.

UI is a bit rude still, it's in Winforms. WPF is so much nicer, but can not run on Mono.
