Get MAC address of device

I'm writing a Windows Phone 8.1 Application that discovers nearby Bluetooth Low Energy devices.

foreach (DeviceInformation device in devices)
{
    BluetoothLEDevice bleDevice = await BluetoothLEDevice.FromIdAsync(device.Id);
}

Everything works fine, but the bleDevice.BluetoothAddress property contains a ulong type, while I need a string type, formatted like a Mac Address.

Example:

bleDevice.BluetoothAddress: 254682828386071 (ulong)

Desired Mac Address: D1:B4:EC:14:29:A8 (string) (that's an example of how I need it, not the actual Mac Address of the device)

Is there a way to convert the long to a Mac Address? Or is there another way to directly discover the Mac Address without conversions? I know there's a tool named In The HAnd - 32feet that could help me, but as of now Windows Phone 8.1 is not supported.

Here is a way of doing it:

var address = string.Join(":", BitConverter.GetBytes(addressAsUInt64)
    .Take(6)
    .Reverse()
    .Select(b => b.ToString("X2"))
    );

There are numerous topics you can find through Google and here on StackOverflow. Anyway, here's one way to do it:

ulong input = 254682828386071;
var tempMac = input.ToString("X");
//tempMac is now 'E7A1F7842F17'

var regex = "(.{2})(.{2})(.{2})(.{2})(.{2})(.{2})";
var replace = "$1:$2:$3:$4:$5:$6";
var macAddress = Regex.Replace(tempMac, regex, replace);
//macAddress is now 'E7:A1:F7:84:2F:17'
