I am working on rebuild and setup new system OP 2.1 on RPI4
I want to check as much as possible on the desk at home, before replace one system by another on the boat.
Now I have an issue with STW and True Wind information.
Goal: make sure STW and True Wind information correctly transmitted converted from signalK to NMEA and shown in OpenCPN.
Current state: Neither True wind or STW are not shown.
What I am doing:
To be clear, most sensors IMU,Apparent Wind,Pypilot,GPS are real and connected to RPi but no DEPTH and STW
STW value I simulate by "Signal K delta simulator" and send value 1..1.2 to navigation.speedThroughWater.
Should it be in m/s? Should it be just number?
I can see in SignalK Data Browser: navigation.speedThroughWater 1.33295
I setup in "Convert Signal K to NMEA0183" plugin VWT, VHW, MWV apparent and True, sentence to generate.
What the problem:
STW and true wind is not displayed on OpenCPN dashboard
VHW, VHT,and MWV true messages ate not observable in NMEA debug output from 10110 port
