It will be a TCP connection, and if you have OpenPlotter configured as an access point, the address will be 10.10.10.1. Port will be 10110. Alternatively, you can configure a SignalK connection.
To determine what addresses and connection types are available to you, you can use the Network app and click "Addresses and Ports" on the top row. You'll get a list of all available addresses and ports.
OK, I understand that on the laptop running a version of opencpn, I create a new "network" connection, select TCP, set the address and port as you say. Do I need to select "recieve input at this port"?
What, if anything, do I do with the RPI opencpn connection? Don't I need to create an "output" connection from the RPI?
Also, I thought I was supposed to use a UDP connection (not TCP) because TCP can only be recieved by one connection, per the documentation. At least that is how I read it.
Thank you kindly!

Connect the phone/laptop/tablet to the Pi's WiFi Access Point and start RealVNC viewer, point it to whatever is the IP address of the Pi's access point. You can control OpenCPN from the remote device too.
That was my initial plan. Unfortunately, the RPI has massive lag due to heat build up, even with a fan and heat sinks, so much so that it is unusable as a chart plotter in the summer months. So, VNC'ing to another device is not useful.
Instead, my plan is use the RPI as a data hub and wifi the data to a laptop or phone or tablet running its own lag-free version of openplotter.
