Creating custom NMEA sentence

[PaddyB]

PaddyB, if opencpn digest $OCMDA sentences, it must also digest $WIMDA. 2 first characters do not define the sentence type, that is the talker ID. Maybe the plugin do not support MDA sentences. Plugins are independent from opencpn core and they support different sentences.

Very important info: https://opencpn.org/wiki/dokuwiki/doku.p..._sentences

Definitely we need a data logging tool on OP core...

I think there's something a bit odd with the logbook konni, I've had it working before with WIMDA sentence but not a IIMDA sentence exactly the same,,,

The plugin says something about it it preferences:


Can't get it working now , and it crashes on a win10 laptop when trying to OK after selecting that box. 
Anyway, I think it's more an opencpn question rather than openplotter. 

Also failed completely trying to send anything to kplex/openplotter from node-red, tried virtual com ports with socat in a linux terminal, which would show up as a dev/pts/3 device and stream data looking at cat but nothing from the nmea diagnostic. 

WOW - from sadness to joy!  Just double checked everything, changed the SK-base-d.py file so it outputs WIMDA sentence from nmea generator instead of OC and it works!! 
Weird!
