I have an issue with the Pixhawk software. I've used APM Planner 2.0 on a Mac successfully until the moment, but I got stuck into one issue. The radio signals aren't received at all by the software, I get nothing:
The usb connection does work (I have calibrated the accelerometer and the compass and I receive GPS data), the LED on the R6208SB receiver is green and I have the "MULT" channels selected on the Futaba Radio. Do you know what could cause the bug on APM Planner?
