How to check status of bluetooth in Windows Runtime?

There are some odd ways, like checking for pair devices and catching exceptions to see it if is on or not. 

if ((uint)ex.HResult == 0x8007048F)
{
   var result = MessageBox.Show("Bluetooth is turned off.\nTo see the current Bluetooth settings tap 'ok'", "Bluetooth Off", MessageBoxButton.OKCancel);
}

But I see there is a new BluetoothConnectionStatus api but don't know how to use it.

It's probably something like this:

using Windows.Devices.Bluetooth;
// look for any paired device
PeerFinder.AllowBluetooth = true;
// start looking for BT devices
PeerFinder.Start();
PeerFinder.AlternateIdentities["Bluetooth:Paired"] = "";
// get the list of paired devices
var peers = await PeerFinder.FindAllPeersAsync();
var peer = peers.First(p => p.DisplayName.Contains("my_bt_device_name"));

var bt = await BluetoothDevice.FromHostNameAsync(peer.HostName);
if (bt.ConnectionStatus == BluetoothConnectionStatus.Connected)
{
    // My device is connected
}
