It is not clear if I can help you. I got a question about showing the the distance to a waypoint and heading in MXTOMMY KIP. Which is a display of SignalK.
Waypoint data is generated in OpenCPN and you have to transfer this data to the SignalK server.
This is possible. The data comes from OpenCPN in the form of NMEA183. The NMEA item for Waypoint etc is RMB.
This how I have done it:
In OpenCPN connections, make a second connection. Network UDP localhost port 2000. Outgoing.
Go to Input/output filers and remove all the items and take only the one you need. RMB was not on the list (right site 3 dots). So I had to add RMB.
Now go to the SignalK server. Login and go to connections. Add new connection. Give item a name (here called way) NMEA183 UDP localhost port 2000. Restart.
If i now make a waypoint in OpenCPN and give goto command. It shows up in SignalK format and can be used by MXTOMMY KIP.
Perhaps you can use this setup and change it for your purpose. If the data is available in SignalK is you can convert this to NMEA2K.
Image with an example of distance and heading to the waypoint. Data form OpenCPN to SignalK.
