    Hi,

    I want to send UDP packets with information from an IMU to the motion platform. I have a C# code which is sending the information to IP 127.0.0.1 and port 4123 and I can confirm the data being sent to that port through Wireshark, however an error message (ICMP) in Wireshark says that the port is unreachable. How do I make sure that the UDP packets reach the motion platform, 6DOF?

    I've seen a few plugins, but all of these are patched to a game. In my case, I don't have a game, only my own C# code.

    Thank you in advance!

    I would create a udp listening test app in c#. listen to the packets. and make sure you can decode it correctly.
    https://docs.microsoft.com/en-us/dotnet/framework/network-programming/using-udp-services

    That would at least confirm that you are sending the packets right.And that it is possible to consume them.

    I had started down the IMU to sim path a few months ago, I was going to pull the IMU data off a drone and stream it though the Rx telemetry stream. then with FPV goggles fly a drone and feel the flight.

    Good luck!

    Thank you for the response. I managed to set up the communication, I wrote my own plugin for Simtools and patched it with my C# program which sends the UDP packets.
