NMEA into KPLEX from node-red?

[PaddyB]

How do I do that? Tried every combination of ports & ip address I can think of but nothing shows up in the diagnostic window. NMEA message is from another thread - $WIMWV,28,R,4.7,N,A*04

Node-red - 

Code:

Thanks, that works, and helps a lot or something else i was looking at  but not for this..

Still can't get a NMEA essage from node red into KPLEX.  I have a tablet running an app called shareGPS which is set to send NMEA gps  messages to 10.10.10.1 port 50000 - works fine, streaming GPS NMEA messages in the diagnostic for a UDP in set to 10.10.10.1 port 50000. 
I turn that app off then from node red on a laptop run your linked node red tweaked a little - works fine as well, signalk being seen on openplotter. 

Send a copied GPS nmea sentence to 10.10.10.1 50000 (with added \n) and nothing in diagnostic. Turn off that entry in openplotter and the message shows up in node-red on the Pi. So getting to the Pi, just not showing up in KPLEX. 

Odd....

Got there in the end, that took a bit of trial and error 

So to send an NMEA message from either node-red or an ESP8266 over UDP the message needs both a carriage return and linefeed - $NMEA_MESSAGE\r\n

cool i kept failing at it i was starting to think of sending to a virtual serial port...
