Is it possible to enter coordinates of a Hemisphere GPS connected to a serial port of the computer and be able to see it in the Overlay of the navigation screen?
You have to send NMEA sentences GGA to 192.168.2.2:27000 by UDP.
That means you have to use a program to listen to serial port and resend by UDP:
Note that it is topside position you send by doing this way, not the Sub position.
After having this work you can setup QGC to display lat and long.
Thank you very much, you have solved the problem for me!
