建立藍芽 LE 廣告

此示例顯示如何從前臺的 Windows 10 裝置通告自定義有效內容。有效負載使用一個組合公司（標識為 0xFFFE）並在廣告中通告字串 Hello World。

BluetoothLEAdvertisementPublisher publisher = new BluetoothLEAdvertisementPublisher();

// Add custom data to the advertisement
var manufacturerData = new BluetoothLEManufacturerData();
manufacturerData.CompanyId = 0xFFFE;

var writer = new DataWriter();
writer.WriteString("Hello World");

// Make sure that the buffer length can fit within an advertisement payload (~20 bytes). 
// Otherwise you will get an exception.
manufacturerData.Data = writer.DetachBuffer();

// Add the manufacturer data to the advertisement publisher:
publisher.Advertisement.ManufacturerData.Add(manufacturerData);

publisher.Start();

注意：這僅適用於前臺廣告（應用程式開啟時）。
