Hey guys,
I allready posted about my issue at OpenMarine forum but it seems this might be the best adress. I have my N2k gateway paired to RPi4B with OpenPlotter3.
My backbone is done with both terminating resistors and my E80 Raymarine is the only device on the bus. The issue is i can see the output of the SK-N2k plugin with PGN's and everything but after i open signalk:stream canboatjs there is no output. The funny thing is that my TX counter is actually moving on the interface itself (on the OLED) but my raymarine is not detecting any device on the bus or seems to not be getting anything sent through the bus.
I have tried setting canboat/canboatjs, different baud rates, ... tried disabling enabling, changing USB ports, cables, ...
I have the gateway for some time now but spent some time installing it on my boat now and configured SK on the boat also. Any advices what else could i try?
I have the engine hat also connected and i can see also the engine parameters PGN's being outputted from the SK to N2k plugin, pressure, sog&cog, position, ... but nothing makes it to my plotter actually. I tried dismantling the enclosure today to check for any wrong wiring on the N2k connector i ended up soldering the N2k header (from the ESP32) directly to the N2k cable and tried again - same result.
Any advices or ideas what to check? If i open CAN-bus app on the OP3 and try unblocking PGN's it also says that i should reset the device or change the baudrate since no PGN's are enabled.
