Hi Team,
My goal is to configure wireless in Yocto Linux automatically when the system starts, but I am having trouble.
In accordance with expectations, the configuration is working properly, and the client is also connecting, but immediately it gets disconnected.
Kindly let me know if I am missing anything.

The steps I followed,
Step1:
Added custom recipe file and my script in systemd folder.

Sorry for the delay. This issue not yet solved. Am in building core-minimal-image and adding packages one by one. Now am stuck with .NET build.
Hi @krsuresh,
I hope you are doing well.
