h2olove - Troubles with NMEA2000 data connectio...
Troubles with NMEA2000 data connection on can0, several NMEA2000 devices failing just because of the signalk NMEA2000 connection being added to the NMEA2000 bus. I tested it on some friend boats and it works there without issues, only on my network I have those drop-out.
I'm using NMEA Source Canbus (canboatjs),
interface can0,
Use Can Name in source data off
Override timestamps off
No filters
Does anyone have experienced this issue?
Or has anybody a tip or hint what could be disturbing the NMEA Network?
Any info would be much appreciated.
Thank you

The network is terminated properly?
Yes, it is.
I tried to initiate the canbus as read-only on Linux, it was a bit better but still producing dropouts.
If it worked fine on another boat, I’d be surprised if the issue was with this device.
I had issues on another boat with a lots of connected devices to the NMEA2000 bus. it looks Li, e the signalk canbus connection is sending some data… could this be? I disabled the sk to Nmea2000 plugin, use only derived data, and no other plugins.
Does the issue happen if sk is not running?
Good question, i will try it out. Thank you
Without sk running no problems. Are my canbus settings incorrect?
