    error there is a mavlink version or baud rate mismatch.


      I followed all the steps in https://github.com/intel-aero/meta-intel-aero/wiki  to connect the RTF with QGC on my ubuntu laptop. But i got an error message that QGCMessageBox (unit testing) "MAVLink Protocol" "There is a MAVLink Version or Baud Rate Mismatch. Please check if the baud rates of QGroundControl and your autopilot are the same."



      Over on the RTF drone I see this after the gst-launch command:

      root@intel-aero:~# gst-launch-1.0 v4l2src  device=/dev/video13 do-timestamp=true ! video/x-raw, format=YUY2, width=640, height=480, framerate=15/1 ! autovideoconvert ! vaapih264enc ! rtph264pay !  udpsink host= port=5600

      i found no ways to match the baud rate of autopilot with qground control.Also i tried to

      disabled the MAVLink router by running

      /etc/init.d/mavlink-routerd.sh stop but unfortunately i found no file named mavlink-routerd.sh in init.d directory but have a file named mavlink_bridge.sh in the init.d directory.
