      the error mentioned above was caused by the voxl-px4 server, once I disabled it was solved.
      Still I was not able to see the data from the external FC

        now it is getting data from fc , it was a issue with baudrate, the J18 port can not handle 3000000 baudrate.
        still i am facing an issue, where the QGC is not getting connected, the qgc is loading,then getting disconnected, again regaining connection this is going in a loop.
        I tried increasing the udp_mtu still no change, same behaviour.

        The error is mentioned below.

          @Jetson-Nano Can you try a lower baudrate, like 57600, and see if that works better?

            @Eric-Katzfey I tried lower baudrate also, the behaviour is similar.

              @Jetson-Nano Do you still get those messages from voxl-mavlink-server about dropped packets from external AP?

                    @Eric-Katzfey No I was using the Microhard module. Irrespective of the communication module, these many time should the sysid change and the packet lose should not occure, right?

                      I changed the Mavlink version to what you had mentioned here, I felt the errors were similar
