Hello,
I made several more changes to my nav system. I am now not completely sure that the radar was on for the wireshark I sent, But I have fixed that and tied the
remote turn-on line to
battery voltage so it is always on when the circuit breaker is on. I tried connecting the compass back in via the
NMEA 0183 instead of N2K and updated the firmware in the gofree router but none of these things helped.
I then re-installed just the Radar pi 5.0.2 Beta1 and I started to get the "Scanning interface 192.168.77.59" in the info box and it connected in maybe 10 seconds. It had previously reported the correct version in the header of that box but had reported "initializing" in the box.
I had completely uninstalled both OpenCPN and the Radar plug-in and deleted the config files and installed OpenCPN fresh with the 5.0.2 Beta1 plugin. I had tried the same but installing the Radar Pi 5.0 first and the 5.0.2 after without success. The one that worked was just the radar 5.0.2 re-install again after I had tried and failed to connect many times.
I retried the different compass connections and have turned everything on and off to try to get it to fail again but it now connects reliably. I am somewhat mystified about what changed with the last re-install. I'm also not sure I have provided you anything actionable, maybe look at the default initializations? or maybe the problem is completely my mistake someplace, but my system is now working well, thanks.
Eric
