AloftWx v0.9 Beta released

Postby legoboyvdlp » Mon May 20, 2019 5:31 pm

This is now ready for testing:

https://github.com/legoboyvdlp/aloftWx/ ... /v0.9-beta

To install, download the files and put in a folder.

Then, install wgrib2 (not GPL or compatiable afaik so cannot distribute) - for windows:
ftp://ftp.cpc.ncep.noaa.gov/wd51we/wgrib2/Windows_64/ (for 64 bit)
or
ftp://ftp.cpc.ncep.noaa.gov/wd51we/wgrib2/Windows_7 (untested, may work for 32 bit)

Then, finally copy local_weather.nas to FGDATA/Nasal/local_weather (be sure to back up!) and copy aloft.xml to FGDATA/Protocol.
Add these to the command line:
Code: Select all
--generic=socket,out,1,localhost,5550,udp,aloft
--generic=socket,in,1,localhost,5553,udp,aloft


I will not show instructions as to how to use it to see if it is self-explanatory or I have to add some documentation / guides :)

And this is not a final release - I hope to eventually predict your heading and add nodes farther ahead.

is there a linux flavor of wgrib2?

Wkitty, I'm sure there is somewhere, not so sure where though, sorry.
This seems to have information about compiling: https://www.cpc.ncep.noaa.gov/products/ ... tions.html

Ok, I'm testing at the moment, got the grib thing working and after some fiddling downloaded a cycle. Then I pressed 'Load downloaded file', this seems to work. Then I pressed 'Parse loaded .grib2 file', but the bar gets stuck at 50%. When I press 'Connect to FG', nothing happens. Can you help me out?

I think that's a bug. It's meant to go to 100%, not 50%.

Connect to FG automatically receives data from FlightGear and opens the connection so it can parse the grib file and send the data back. It will listen to the latitude and longitude properties and re-parse every time the rounded value changes from one interval of 0.50 to the other (e.g. from 11.5N to 12N it changes at 11.75N and that triggers the script to parse data and send it to flightgear

Do you see any output in the console window?
If it's successfully running you should see some messages with the command line and output of wgrib2.

Even if you don't (are Release builds different to Debug builds?) you should see "adding aloft point for X, Y" in the flightgear console (X and Y being the latitude and longitude)

Do I have to start wgrib2.exe too? Because when I start it (Win10 64 bit), I briefly see a command window, but it disappears before I can read what 's written in it.
In the FG console I don't see any aloft outputs.

You can try wine. It should works.

No, you shouldn't need wgrib2.exe as the app will open wgrib2 automatically.

Did you set up the ports in the options window and use:

Code: Select all
--generic=socket,out,1,localhost,5550,udp,aloft
--generic=socket,in,1,localhost,5553,udp,aloft


(changing ports to match)?

Ok, I assumed the ports were configured right out of the box, but it seems 5554 and 5553 are used instead of 5550 and 5553. Now when I press connect to FG the program closes, but I don't seem to get the real world aloft winds.

The parsing bar still hangs at 50%

Just to be sure: I've selected 'live weather' and 'aloft waypoints' in the advanced weather menu. Are these the right settings?

The program certainly shouldn't close. Maybe that's a bug. To confirm, you did add the path to wgrib2 (not to the .exe but to the directory) to the file? And was there any error message?

Regardless, I've fixed the bug with the progress bar (and I will also set the default ports correctly) and will make a new release.

You want to use aloft waypoint interpolated - so I think thats the right one, yes. It will use both live weather and aloft winds.

When I use aloft waypoint interpolated I get a warning in FG: "wind model not supported, aborting."

After clicking on 'Connect to FG', I was able to quickly make a screenshot of the console window of aloftWx.exe, before it closed (about half a second later):

Ok, just now I see that it is in Dutch. The text reads:
Unprocessed exception: system.formatexception: the format of the inputstring is wrong.
at system.number.parsedouble(String value, Numbers...)
at Aloftwx...
--- end of stacktracing from previous location where the exception occured ---

Ok - thanks - I'll try and fix that.

As for wind model not supported maybe Thorsten will know why; I don't. You are using live METAR?

Maybe it abborts because no data is fed into it yet? I always use aloft waypoints because I had that error maybe 4-5 years ago for interpolated so assumed this was not implemented for live weather. (so I think this has nothing to do with your aloft wind program :) )
