[CA] [CA11] NMEA0183 Wind Steering on ST2000

[bretthoward]

So with RS422 it does now go into W mode! Progress!

However it says W but it then shows the heading as the angle not the apparent wind angle.

Then as I turn the unit it seems to steer as though it is just in standard A mode (turns one way as I rotate one direction then turns the other way as I rotate past the set point in the other direction). This is all happening while the unit is sending the same fixed wind direction over and over...

I then wrote a module that fed the unit 45 degrees for 10 seconds then changed to 50 degrees for 10 seconds followed by 40 degrees for 10 seconds. The unit just some what pulsed every so often but remained fairly still steering wise... Perhaps the ST2000 is filtering out the very consistent data and assuming that it is fake?

Is their a recommended rate at which these NMEA0138 wind sentences should be sent?

Also I presume there is no issue with the unit sending both MWV and VWR sentences for every message interval? Seems that it would just ignore extra information.
