Hello

Welcome to Microsoft Q&A!

how does this API choose which channels to use and can this be configured?

The API does not provide direct control over which channels are used for Wi-Fi Direct advertisements. The channel selection is managed by the underlying Wi-Fi driver and the operating system.

Is it assured that only valid channels for the country in which windows is being used?

Yes, the API ensures that only valid channels for the country in which Windows is being used are selected. The Wi-Fi driver and the operating system are responsible for adhering to the regulatory requirements of the country, ensuring that only permissible channels are used

Are only 2.4Ghz channels used?

Wi-Fi Direct typically uses both 2.4GHz and 5GHz channels, depending on the capabilities of the Wi-Fi hardware and the regulatory requirements of the country. It is not limited to only 2.4GHz channels.

Thank you.
