Check if bluetooth support available

You can use BluetoothLEAdvertisementWatcher class.

var _advWatcher = new BluetoothLEAdvertisementWatcher();

_advWatcher.Start();
Thread.Sleep(100);
_advWatcher.Stop();

if (_advWatcher.Status == BluetoothLEAdvertisementWatcherStatus.Aborted)
{
    Debug.WriteLine("Bluetooth is disabled or not available");
}

You can even register for advertisements. If Bluetooth is disabiled or not available you will receive no advertisement.

// before _advWatcher.Start()
_advWatcher.Received += AdvWatcher_Received;

private void AdvWatcher_Received(BluetoothLEAdvertisementWatcher sender,
    BluetoothLEAdvertisementReceivedEventArgs e)
{
    Debug.WriteLine("Advertisement received. Bluetooth is available!");
}

Hope this help!
