Possible to create AtoNs with SignalK API?

Where is the best place to look for the SK data model? I looked through the documentation but didn't see anything describing what to send for PGN 129041 - Aids to Navigation Report. Looking for Position Accuracy and AIS Transeiver Info.

Awesome. I'll look into it. My marks are showing up on OpenCPN and a Raymarine MFD. Just have to figure out why the Garmin is being stubborn. But that's not a SK issue. Thanks again.

So if only the position changed, I could send that but not virtual, name, etc.

Don't deltas just modify a previously sent packet?

Possible to create AtoNs with SignalK API?

I will base my request on your example. In the docs at https://signalk.org/specification/1.7.0/doc/request_response.html#websockets-and-other-full-duplex-protocols, it talks about a response to a websocket request. Should I not expect one?

Yes, I see both in data browser. Maybe I don't have forwarding correct. An example would be awesome as well. Thank you!!

I still seem to be missing something. Sending auth request works, but no response to sending AtoN. What am I doing wrong?

We have an existing app in Python, so it will have to start there I think.
