strange response from 2 Garmin NMEA products

So, raspberry pi, stretch, Opcpn 4.8.8 with a Maretron USB100 with a Garmin gps and a Garmin (Airmar) depth gage. Gps will read when all sentences are read, and depth gage will read when no sentences are read. Cannot get both to read at the same time. ??????????????

I don’t really understand the problem. Can you explain in more detail? Like this doesn’t make sense to me: “gps will read when all sentences read”. Explain the steps necessary to reproduce the problem.

Data are coming from a Maretron USB100. I have a Garmin gps and a Garmin (Airmar) depth gage. Using software, the output of each sensor is being properly output from the USB100.

Connected via /dev/ttyACM0, proirity1, 4800 baud, input, and accepting only sentences. I have selected all sentences and the gps can be displayed through the dashboard, but the depth reads zero. If I select ignore sentences and select all available sentences to be ignored, the depth reads correctly in dashboard but the gps ceases to be read. I agree that this makes no sense and only accidentally discovered it.

I would very much like to read both at the same time. Thanks

I finally thought to try 'ignore sentences' and select nothing to be ignored and both gps and depth are now properly displayed in the dashboard.

Thanks.
