Hi. I'm putting together a software autopilot
. I have no trouble reading the NMEA
*output* from OpenCPN
and having the software
follow a route
. I can read the RMB to see the current destination
lat/lon value, and when the boat
has entered the "arrival circle".
I'd like to know if OpenCPN
accepts an *input* NMEA
string that tells it to track to the next waypoint in the route
. If it does exist, then the exact format of the string? I imagine this is a standard string output from most existing autopilot
Second: I notice that OpenCPN seems to automatically track to the next waypoint, apparently when the boat
moves out from the arrival circle. Could someone confirm this behavior, and is there any way to disable it? I couldn't see any option to do this in settings, or to set the radius of the arrival circle.
