Creating custom NMEA sentence
#1
I have a BMP180 working, at the moment the NMEA generator makes an NMEA sentance which opencpn dashboard can read-
$OCMDA,,,1.018,B,22.3,,,,,,,,,,,,,,,*3D

What I want to do is have the logbook konni to automatically record pressure as well - do do this apparently it will look for a sentence like..
$WIMDA,30,I,1.02,B,10.1,C,,C,,,,C,158.69,T,,M,3.89 ,N,2,M*37

So -
How do I get a data feed created in node-red to be seen by openplotter so I can make a new nmea sentence? I can get node-red to see a udp feed it's created itself to be seen by node-red but can't get it into openplotter.
Or is there a way for force the nmea generator to write a sentence like$WIMDA,.... instead of $OCMDA,,,1.018,B,22.3,,,,,,,,,,,,,,,*3D ?

I'd like to get node-red working just to know how Smile
TIA
