I am using node-red to bring down a lat and long from thingSpeak, putting it through a node-red "function" where it is converted to an NMEA 0183
RMC sentence. I am then trying to input it to openCPN
on the same PC via UDP. I have set the port to 192.168.0.105:10110 in node-red and in openCPN. Opening the NMEA
Debug Window nothing appears to arrive in openCPN. What am I missing please.
