Well, firstyl you need to ensure that the GPIO pin has been programmed to be an input, and it's of the right bluetooth type. As I said before, GPIO pins can be input, output; they can be connected via an internal mux to a variety of "behaviours". Take a look at the gpio configure code in ath9k to see more. THen you need to ensure the bluetooth coexistence registers are programmed so that btactive will correctly stomp wifi traffic. THat's all I know for now. Sorry. adrian
