Hi,
I've a problem with signal K data in OpenCPN. I've the following setup:
AIS: Quark-Elec A033 Bi-Dir with WiFi Multiplexer and SeaTalk
Multiplexer: Em-trak b953
Plotter: Raspberry pi 4 + openplotter 3 image.
I also have a Nasa Clipper Wind device but also without this device connected a get the problems.
As soon as I connect data from the multiplexer via usb to my raspberry OpenCPN freezes after half a minute. I connect the data to OpenCPN via signal K. In signal K I don't see any error and I see a nice regular update of the data.
Has anyone experienced something similar or any idea what could cause this behavior.
Kind Regards,
Anna
I've had crashes with both NMEA0183 and signalk connections to signalk enabled at the same time. Do you need signalk data in opencpn? NMEA0183 covers most data opencpn can use.

Thank you so much for the quick reply!
I've only 1 connection in opencpn at the moment, this is my signalk connection, but I could try to use the serial data connection in opencpn. I have signal k because I like the dashboard from signal k as well.
Do I understand correctly that adding a serial connection as described here:

could you open opencpn typing "opencpn" in a terminal to see if any error is raised in the terminal when freezing?

Thanks for the reply! I'll try it this weekend when I'm at my boat again
on openplotter I connected the signals of the boat's instrumentation (gps, depth, water temperature, speed, wind direction, etc. etc.). all signals are managed by signalk and are active. while opencpn reads them regularly, Avnav does not receive them from signalk. so yes Avnav all displays are cleared and the gps signal is absent. Can anyone tell me where the problem lies? a thousand thanks
Did you guys ever find out what was wrong? I can't use signalk either, because within two minutes all of OpenCPN freezes...

It's a known issue with OpenCPN, the developers have committed a fix very recently which should be in the next OpenCPN release:
