Kplex lost contact with signal k

[Littlechay]

this has me stumped so far.

here is the screenshot of the nmea0183 tab

any ideas anybody?

So how does the data get from signalk to nmea - is that through the nmea 0183 generator? 

I only have 1wire temp sensors and to see that in opencpm I need to map the signalk data to water temperature so the dashboard can display it, the other data sorry dunno . Looking at the signalk kplex output it looks like signalk just sends out the basic gps data out over nmea, do you need to set up the other i2c & 1w in nmea 0183 generator?

Openplotter has some sort of "gateway" that generates NMEA sentences from the sensors on I2C and 1W interfaces. There is only a need to fiddle with sentences in the 0183 generator if the defaults are not working. 

Anyway I solved the mystery .. well not exactly solved.. OCPN's NMEA filtering was blocking instead of accepting. Changing the filtering in OCPN's connections panel from accept to ignore (or vice versa) got everything flowing again. (seen this before with OCPN and should have got to it as the cause sooner, but was stumped by some red herrings in OP).

However some mysteries still remain.. such as why I couldn't see the rejected messages in OCPN's NMEA monitor window and why I couldn't see them in the NMEA 0183 diagnostics in OP (looking at the diagnostics for the TCP output stream for OCPN).

All up and running again but with questions hanging.
