I have a Pi 4 running off a USB SSD drive (as the boot drive) The Software is the latest Image with all updates from Openplotter
I was hoping to add a Moitessier Hat, but that is now on the back burner, so I added a loose I2C board to get a few of the sensors, and the rest was supposed to come via WiFi from the boat sensors.
So I have a Compass , 3 axis accelerator(supplying Pitch & Heel) , pressure sensor and Temperature sensor all working well on the I2C network . They feed data into Signal K, and that data appears in Open CPN without any problem on the default connection setup
In Open CPN "connections" I add a WiFi network connection to the boat WiFi network, but no boat data appears in Open CPN. This same WiFi connection works well with my android tablet on Open CPN, and with my Windows laptop with The same version of open CPN as the Pi has (latest ).
Both android and windows devices use the exact same WiFi settings and All the wind, GPS, Depth, AIS data is available in Open CPN.
When I apply the same connection settings to the Pi4 Open plotter 2 system, then I have no boat data whatsoever.
I tried in desperation to just get GPS data via a USB "mouse" type GPS. This particular USB GPS device has served me well on open plotter 1 with a Pi 3, but will not work with the Pi 4. If I setup a USB serial connection In Open CPN and also perform the "sudo usermod -a-G tty pi" I have data appearing in the NMEA debug window immediately, but no position information on Open CPN
I even tried sending the serial GPS data to Signal K, because to me Signal K already had a working path to Open CPN. That never worked either. Signal K seems to indicate that it is relieving USB GPS data, but it wont appear on Open CPN
I have run out of places to RTFM, so now hopefully someone can point me to a possible setting I have got wrong
