Hello,

Welcome to Microsoft Q&A!

Update:

I need the legacy settings to be enable for my device to connect with an SSID, but I do not need to broadcast this SSID.

I have to say that currently there is no API in the WiFi direct could just hide the SSID as you want. Currently what we could do is to disable the legacy mode. I'd suggest you submit a feature request about this in the Feedback Hub. You could find the Feedback Hub in the Start Menu. Please select Developer Platform->API Feedback as the category when you submit your request. The related team will check the request.

If I understand you correctly, you want to hide your device when other devices are just scan for normal WiFi, right? When your app is broadcasting advertisements, you want to make your device only available for those devices which support WiFi Direct.

If it is, you could take a look at the WiFiDirectAdvertisement.LegacySettings Property, it contains a WiFiDirectLegacySettings Class, you could set the WiFiDirectLegacySettings.IsEnabled Property to false to disable legacy mode, so this device will not act as a normal Wi-Fi access point. You don't need to hide the SSID because the noraml WiFi scan should not be able to detect your device after setting this property.

You could do it when you are creating the WiFiDirectAdvertisementPublisher object, like this:

WiFiDirectAdvertisementPublisher _publisher = new WiFiDirectAdvertisementPublisher();  
_publisher.Advertisement.LegacySettings.IsEnabled = false  

You could also take a look at the official WiFi Direct sample. In the scenario 1, this property has been set to true to enable the legacy mode. You could set it as false in your scenario.

Thank you.
