Nokia Treasure Tag and Lumia Icon

File this under ‘beware early adopters’, but in case you haven’t heard, Verizon has started selling the $29.99 Nokia Treasure Tag accessory. Pairing via NFC and Bluetooth, the little gizmo allows you to track via HERE Maps whatever possession you attach it to, making it perfect for your keys or new baby (I jest).

Unfortunately, if you buy one today – like I did – then you’ll find yourself with a useless purchase if you’re on Windows Phone 8.1 Preview for Developers. That’s because it says you need Lumia Cyan for it to work. As a reminder, Lumia Cyan is the forthcoming firmware update that will roll out with Windows Phone 8.1 in the coming weeks and months.

As it turns out, the Store warning for the app denoting the requirement is accurate.

So why doesn’t it work?

Windows Phone 8.1 Preview for Developers disables Bluetooth 4.0 LE, which is needed for this contraption to work. Not many people know that but that’s what happens. Bluetooth 4.0 LE will obviously come back, that’s what the Cyan firmware will do, but until then early adopters are out of luck.

Nokia Treasure Tag and Lumia Icon paired

Ironically, if you’re just a regular Joe, who has an out-of-the-box Lumia Icon with Windows Phone 8.0 Update 3, everything will pair up and work just fine (see the above photo).

The good news is if you did buy the Treasure Tag, you’ll only have a few weeks (or months?) to wait until the proper Windows Phone 8.1 update with Lumia Cyan firmware arrives, which will make it all worth it. I’ll just have to make sure I don’t misplace my Treasure Tag in the meantime.

I’ll play with Treasure Tag on my other Lumia Icon and will share my thoughts in a few days.
