The other thing you can do is to use the NMEA generator to generate test AIS strings for OpenCPN. You'll have to find an example AIS string and have the generator create it for you on a regular basis.
It may be that you need to get a RPI3. Does OpenPlotter even work on an RPI2?
Thanks Why wouldn't it work on an RPI2 it was developed before the RPI3 existed.
Is the NMEA generator the same as the test NMEA that the hat can generate? would the HAT be sending the TEST NMEA sentences out on the serial interface?
