I think this is because the signalk to nmea plugin has a heading sentance checkbox, but there is no pitch/roll nmea sentance, hence that data never gets to openplotter?
If heading no longer working check the signalk to nmea plugin is enabled and mag heading sentance checked, then look in the openplotter nmea dialog, you should see the heading sentance.
You will not see Pitch, Roll or or heading in some cases by default. This is because of the sentences that OCPN knows how to decode (or that it doesn't know) .
For example without HDM sentence you'll get heading either on the plot (the ownship icon) or on the dashboard but not both - I don't remember which way around that is.
The solution is to define the sentences in the NMEA sentence builder (found in the Tools menu). Remember that the angles as fed from signal K are in Radians so you have to convert to degrees by multiplying by 180/pi (or approx 57.296 ).
