Unable to set sim/weather

[krao-MIT]

I'm using Windows 10, Matlab 2021a, and XP11 Version 11.55 (OpenGL).
I'm trying to change aspects about the simulated weather using XPC. For example:

disp('Setting up Simulation');
Socket = openUDP('127.0.0.1', 49009);

sendDREFs( {'sim/weather/wind_speed_kt'} , single(5) , Socket) % <- Doesn't work
result = getDREFs('sim/weather/wind_speed_kt', Socket)

I can change the weather using the GUI in XP11 and I can read the resulting weather based on those changes from the GUI. But I can't seem to make those same changes from XPC. Documentation online states that the variables are "Writeable" (https://developer.x-plane.com/datarefs/).

Any help in determining how to manipulate weather using XPC would be appreciated.

X-Plane 11 does weather in layers so I recommend you edit these layers individually. For this use the DREFs with a [0], [1] or [2] at the end of the property and then you can define the speed, direction and altitude (note that if you want it to be acting on the aircraft it must be set at the same altitude).

In your case you would use the sim/weather/wind_speed_kt[0] DREF
