I have been trying to track down the problem described above today after reading docs on debugging. Managed to locate the following error message on the nmea0183-signalk stream.
It seems there is a parse error in the wind instrument sentence. The sentence is correct with the exception of what appears to be a non-printable/non-standard character that precedes the $ symbol. Data is from NASA nmea wind instrument input to RPi3 using a digital yacht nmea to USB adaptor. Baud rate is correct (4800) and both adaptor and log show I am getting regular data that is correct apart from this spurious leading character (i.e. Wind instrument, MWV sentence, relative wind, 115degrees, speed 0, knots, data valid. As I said above I did get one correct sentence on setting up the input initially but not since.
Does anyone have any idea what may be causing this or how I may remove/adapt to it?
Thanks,
Chris
