Connecting NMEA Wind data from NASA Clipper

Well ...i think that i have tried just about everything by now but it's not working. This can't be a configuration issue, it must be a bug.

I have tried different ways of connecting my NASA clipper via RS422, RS232 Didier-style, RS232 clean (no loopbacks etc)  and i get nice strong blinking green lights and can see the $WIMWV sentences flowing nicely when doing the Auto Setup. I can add the interface in the USB manager, i can create a new entry in the NMEA tab (serial, in, 4800, no filters, apply settings, restart etc) but when i select my new entry and click diagnostic, there is nothing and i get a timeout.

I have tried configuring entries in the NMEA tab selecting all the available ports but there is no wind data on any of the available ports, including the RS232 or RS422 defined port (from the autosetup)

I have also tried to minimize the system, all hats and other sensors disconnected to try to get rid of any interference from them.

The NASA clipper wind system is working nicely on my desktop, displaying changes in the wind direction when i move the vane (yes, i tried that when autosetup was running and the values in the sentences changed !)

So, Kplex is getting the information but open plotter seems not to be capable to handle the information

I would love to see some screenshots from a working NASA Clipper setup (if that exists)

My sailboat is in the water and the mast is going on soon after which i have to mount the Wind instruments on the boat effectively suspending further experiments ,,, :-(  

I would /greatly/ appreciate any kind of help or hints to get this done.

Is the checksum from the nasa OK? I have an older wind sensor from. Nasa which adds a wrong nmea checksum, took a while to find. Sorted it by having an arduino recalculate the checksum. Could you paste one of the messages?

Hi Paddy.

Checksums...I have no information about the NASA messages beyond what i have posted earlier from the auto-setup (MWW sentences) and i see no checksum there. How can i get the logs/messages you are asking for?

My NASA Clipper Wind is brand new but i don't know if the checksums are correct. I think that they mention in Stripydog Kplex Config that you can turn off the checksum locally [checksum=no] in the "Advanced" config so i tried that but it still did not work. 

Sounds a bit ambitious to have an Arduino recalculating the checksums bu i would be interested in trying that if nothing else works, have a few lying around. Of course, it would be nice if the NASA gear was supported by Open Plotter and i really hope that the new hats/sw will support that part of the market.

Tell me if there is something that i can do to help you help me

Hi Paddy, tomorrow i'm doing the same test: connection of NasaMarine Clipper tactical system to Openplotter.
As you can see by the attached file, i'll test two connectivities schema: my preferred one is the option 1 with 2 GPS.
