Please make sure you connect Pin1 to Pin 1 on the Mikrokopter debug port. Both interface
boards have a red LED for convenience, this is not only an operation indicator but a power on
indicator as well, it will only work if a proper and working xBee module is inserted.
When trying to connect make sure you use the correct port on the computer for the MKTools,
otherwise there will be no communication. In our testing we flew the Mikrokopter with 900Mhz
and 2.4GHz xBee modules while remote controlling the Mikrokopter in 2.4GHz Spektrum RC
radio.
