The Windows Phone 8.1 update brings several exciting features, one of which is the support for Bluetooth Low Energy. For those who are unfamiliar with it, Bluetooth LE (also known as Bluetooth Smart) is a wireless personal area network designed to pair wearable devices to your handsets. This means less battery usage.
The Redmond-based giant recently added the Lumia 1520 to the Bluetooth certification process. The Lumia 930 and Lumia 630 are already certified for Bluetooth 4.0 LE and hence are making good use of the advantages of connected hardware devices.
While this feature was originally rolled out with the Windows Phone 8 GDR3 update on the Lumia handsets, the company is now bringing native support for it on all Windows Phone 8.1-powered devices that support Bluetooth 4.0. Once Microsoft’s mobile operating system receives this feature, we can expect several wearable devices such as Fitbit or maybe even an official app for Pebble to arrive on Windows Phone.
