Did my log make anything clear? There are a lot of null's, I know, and I know I'm still in the harbor when the log ran.
It'd make sense to start OpenCPN before I am underway though, and the speed OpenCPN hangs currently just lets me loosen one mooring line.
Is a bit strange. Here in my setup with the input from an NMEA2000 GarminGPS works fine without hiccups.
Canbus is a Canable board or an NGT-1 both running at 250000, RaspiOS64, SignalK 1.44 with an SK connection to OpenCPN. Route info is send back tot the SignalK server.
RPI4 2 GB with the latest kernel version. Is the problem caused by the type of canbus in the system?
