no changes of nmea values at the com port #60

Closed MDeTL closed 5 months ago

MDeTL commented 1 year ago

I have a problem with the nmea values on the com port. If I change a value like the vessel speed I can see that the value has changed in the NMEA Output window. But the real output on the com port has not changed. I used two USB to RS422 adapter to test the output and used hterm to log the transmitted data from the simulator.

I also tested different output intervals but doesn't help.

Baud: 4800 Parity: none Data bits: 8 Stop bits: 1

Have I set something wrong or is it a bug?

I cannot reproduce the issue you describe. I have checked comport output as well as other output channels and the data seen in those streams reflects that shown in the Output window.

I see the correct speed reflected in RMC, VHW & VTG sentences.

Sorry I have written the vessel speed but I mean the engine rpm. If I disable gps, wind, destination and water then is the output much faster.

From what I can see the RPM values are changing. v1.6.1 contains some "tweaking" of the output stream written to serial port which should hopefully address variance in output transmission.
