I have two major inputs in my NMEA
backbone. Both are Garmin
products, a gps
and a depth
gage (actually made by Airmar). Under "Input Filtering" when I choose "Accept only Sentences" and then select all sentences, I now only get the gps
inputs and no depths. If I choose "Ignore Sentences" and then select none to be ignored, I get both gps and depth
inputs. The first choice worked for several years and I must admit I didn't notice what happened when the depth started to no longer be read. I am using a Raspberry Pi and have had this same response with Jessie, Stretch, and Buster using an applicable different version of OPCPN with each. Does this only seem strange to me?
