I am using an APM2 together with the "Xbee Telemetry kit 2.4 GHz" and I am not able to establish a connection via APM Planner 1.1.85 (ArduPlane setting). I always get the error "No Heatbeat Packets Received" and in the command window:
INFO ArdupilotMega.MAVLink - Open port with COM30 57600
INFO ArdupilotMega.MAVLink - 186 Start connect loop
INFO ArdupilotMega.MAVLink - MAVLINK: S wait time out btr 0 len 0

I have tested both Xbees successfully with X-CTU. I can read out both modem configurations successfully and also the loop back test works. The baud rate is set to 57600.
Any suggestions why the connection does not work?
