Connecting NMEA Wind data from NASA Clipper

[PaddyB]

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.

If the Nasa isn't sending line feeds then that's probably not helping or maybe the root cause - have you used node red before? Quite easy, and the debug shows the line feeds which helps and it's quite easy to add them to check if that's what's going on. If you've never used it before someone could talk you through it - node red is great!
