I wrote a GPS-Input-Simulation for testing purposes.
Like you see in the attached Nema-Debug-Window a Nema0183 string $GPRMC... is sent to OpenCPN
over UDP. The colour is black for accepted, but the dashbord doesnt show the send corrdinates and the boot doesnt position.
The same if I send $GPGGA or GPGGL.
I know, that the string dont show the correct Checksum, but therefor I have dissabled the control of the Checksum. There is no other GPS-source conectet to my WIN10 Laptop
and its the current OpenCPN
Can you help me how to overwrite the Position.
