@airsimdevdd, what version/commit of AirSim are you launching along with the set_wind.py script?

Hi @ahmed-elsaharti
Thank for reply here is the version that I use
I am launching airsim in Linux
Along with airsim binary version 1.3.1
And I have installed airsim from official airsim website.

ahmed-elsaharti Mar 3, 2021

@raghu-990, the simSetWind API and the wind simulation feature were introduced in release 1.4.0 (#2867 67d5b6a) which is why they won't work with a 1.3.1 binary.

I'm using PX4 version 1.10.1 as recommended in Airsim official website.

ahmed-elsaharti Mar 3, 2021

I just tried running the blocks binary with PX4 SITL and it worked perfectly.
Did you follow the guide correctly?
Also, I think you need to run PX4 SITL first then run AirSim rather than the other way around

Edit: I just ran into a similar issue, fixed it by switching over to simpleflight (ie: deleting the settings.json file and running airsim) then editing the settings.json file back to the PX4 config and running that
