Mission Planner UDP and TCP/IP Connection

Posted by Warren Mall on October 6, 2012 at 6:26am

I have been trying to get the Mission Planner to accept UDP and TCP/IP inputs.

I keep getting a time out error on a UDP  connection.  I have tried various playback rates and real-time rates, but I always get a time out error.

Is there anything special with UDP and TCP/IP connections?

Thanks,

Warren

    both tcp and udp should work. it is required to be 2 way however.

      I'm using the wifly module connected to my board (crius aiop), the wifly and my pc are connected to a router, mission planner is seeing the udp connection but can't load the configuration, I get connection time out, I think I'm having a problem with port numbers.

        MP replies to the same ip/port that the packet originates from.

          I'm having this problem know that I can't get over, when i try to connect I get this message " getting params(sysid 1,compid1)--> the first image, and the the second message comes up --> the second image,i have set the MP to listen to port 2000 the same that my wifi module transmit on, and i have set the correct baudrate on my wifi module according to the serial on my board ( crius aiop 1.1 flashed with MPNG 3.01 r4), i don't know whats causing this problem.

          Thanks.

            please use something like wireshark to see what is going on.

              I solved my problem, it seems that there is a problem in megapirotng 3.01 r4 serial 2 and 0, when i flashed my board with the mpng 2.8 r3, the connection was established successfully using tcp connection.

                Hello. I'm on a similar project. Which tcp port did you use to connect to it? Have you tried UDP port 14550? Thanks in advance.

      Do you have some example code?

      How do you do a two way on UDP?

    Hi warren, I have the same problem now did you manage to solve it?

    • Warren Mall > Jad Yaacoub March 25, 2014 at 1:04pm

      No.

      I am thinking about just adding another receiver.

      That should be an easy way to bypass the problem.
