Connecting NMEA Wind data from NASA Clipper
#33
Hi,

I feel that i have narrowed down the problems a bit:

Looking at cat /dev/ttyUSB0 i get:

$WIMWV,78,R,10.9,N,A*3A
$WIMWV,78,R,10.0,N,A*33
$WIMWV,78,R,9.4,N,A*0F
$WIMWV,78,R,8.9,N,A*03
$WIMWV,78,R,8.2,N,A*08
$WIMWV,78,R,7.7,N,A*02
$WIMWV,78,R,6.9,N,A*09
$WIMWV,78,R,6.6,N,A*02
$WIMWV,78,R,6.2,N,A*06
$WIMWV,78,R,5.6,N,A*01
$WIMWV,78,R,5.0,N,A*04
$WIMWV,78,R,4.6,N,A*0E
$WIMWV,78,R,4.4,N,A*02
$WIMWV,78,R,4.2,N,A*04
$WIMWV,78,R,4.0,N,A*06
$WIMWV,78,R,3.9,N,A*08

...but without linefeeds (it overwrites the same row in the terminal window). It looks like i get correct information above with the correct checksums from my NASA mast unit

If i look at  cat /dev/ttyUSB1 (which is my GPS) i get nice new lines for each NMEA message - and that is nicely handled by Kplex, shws up in "Diagnostic" etc

Looking at the auosetup in openplotter  i clearly see that it does not read the NMEA input (available as shown above in the ttyUSB0)  from my mast unit correctly - it messes up the checksum and have a problem finishing the autosetup without hanging

So, the raspberry reads the NMEA input from my mast unit correctly but OpenPlotter sees something else - and can't handle it.

What to do... definitely seems like a quite serious bug to me ...  :-(

In my desperation i have now also installed the latest Noob on a new Pi 3+ and tried it out there, but no joy - exactly the same issues. Reads nicely in ttyUSB0 but noting is received/shown/used in open plotter.
