A port of the WiFiDirectLegacyAPDemo to a C# UWP console app

This is a quick and dirty port of the WiFiDirectLegacyAPDemo written in C++ to a C# UWP console app.

Wi-Fi Direct Legacy Connection C# UWP WRL Demo

This sample is a simple UWP console application that uses WRL to demonstrate the Wi-Fi Direct legacy AP WinRT API from a UWP application.

Developers of UWP applications can use this sample to see how to replace the deprecated WlanHostedNetwork* API's with the new WinRT API's. These API's let an application start a Wi-Fi Direct Group Owner (GO) that acts as an Access Point (AP). This allows devices that do not support Wi-Fi Direct to connect to the Windows device running this application and communicate over TCP/UDP. The API's allow the developer to optionally specify an SSID and passphrase, or use randomly generated ones.

The sample is organized up into the following files:

• WiFiDirectHotspotManager.cs : This contains the code that uses the WiFi Direct API. This part may be used as is or modified to fit your application needs.
• SimpleConsole.cs : This is a simple console using Console input to take command line input and start or stop the Wi-Fi Direct legacy AP. It implements the IWlanHostedNetworkListener to handle receiving messages from the API.
• Program.cs : Main entry point that starts the simple console.

Note

• This sample requires Windows 10 to execute, as it uses new API's. It also requires a Wi-Fi Card and Driver that supports Wi-Fi Direct. These API's do not support cross-connectivity so clients connecting to this device will not be able to use it for Internet access.

Note

• Passphrase must be at least 8 characters! Otherwise you will get a message saying "Advertisement aborted, unknown reason"
