Data connetion from a OFNI

[fzamacolam@gmail.com]

Hi all, and thank you so much for this project.

I'm trying to build a sensor that in case of MOB sends to the vessel its position. I'm receiving its position througt a NMEA0183 TCP Client Data Connection in my SignalK. 

The question is: how can I tell to SignalK that the position corresponds to other Vessel or flotant object? (in this case is a MOB).

Thanks a lot!

you have to send this delta message to the signal k server:

Code:

{
  "context": "vessels.urn:mrn:signalk:uuid:c0d79334-4e25-4245-8892-54e8ccc8021d",
  "updates": [
    {
      "source": {...},
      "timestamp": "2017-08-15T16:00:05.200Z",
      "values": [
        {
          "path": "notifications.mob",
          "value": {
            "message": "MOB",
            "state": "emergency",
            "method": ["visual", "sound"]
          }
        }
      ]
    }
  ]
}

"context" is the unique identification of the floating object. You can also use the mmsi:

Code:

"context": "vessels.urn:mrn:imo:mmsi:234567890"
