Hi, I am considering adding some circuitry to a Roomba which would have some extra audio capabilities. Since the SCI command set is somewhat "closed" and the commands which I need to have will be of varying command lengths - the only way that I can think of to do this is to build a micro controller which acts to intercept my custom commands (xml formatted), and pass through the SCI commands directly to the Roomba serial port. So the BT module would connect into my microcontroller board, and it would in turn have another output serial port to the Roomba. Is there some easier way of doing this, or perhaps its already been done? thanks! 'mark
