Sending NMEA 2000 Messages over UDP

[rainman012]

I am trying to send data via UDP to the NMEA 2000 network using the "signalk-to-nmea2000" plugin.
In the debug log everything looks good but the message is never send to the YDEN-02 gateway.

Feb 07 12:07:30 2022-02-07T11:07:30.127Z signalk-to-nmea2000 emit nmea2000JsonOut {"pgn":129026,"COG Reference":0,"COG":0,"SOG":0.016976670967423314}

I also tried to send the very same JSON directly via a simple test tool using canboat. This works. So the YDEN-02 is not the problem.

This is my SignalK server config:

{
  "interfaces": {},
  "ssl": false,
  "pipedProviders": [
    {
      "pipeElements": [
        {
          "type": "providers/simple",
          "options": {
            "logging": true,
            "type": "NMEA2000",
            "subOptions": {
              "type": "ydwg02-udp-canboatjs",
              "host": "192.168.178.43",
              "port": "1457",
              "useCanName": false
            }
          }
        }
      ],
      "id": "yden",
      "enabled": true
    },
    {
      "pipeElements": [
        {
          "type": "providers/simple",
          "options": {
            "logging": false,
            "type": "FileStream",
            "subOptions": {
              "dataType": "NMEA0183",
              "filename": "/dev/ttyACM0"
            }
          }
        }
      ],
      "id": "GPS",
      "enabled": true
    }
  ],
  "security": {
    "strategy": "./tokensecurity"
  }
}

It works when using TCP.

What am I missing?

Many thanks for your kind assistance!

Sorry, UDP connection type does not support two way communication, it just listens for data and does not support sending.

It should be pretty clear from the configuration screen that has no host field. I assume the host field in your setting is leftover from having used TCP previously for this connection.

Ok thanks for the feedback. At least it works with TCP.
Maybe something for further development. Unfortunately I have not much knowledge about Javascript and the code is not self explaining to me. So nothing I can provide in the near future.
