Windows 8.1 supports Bluetooth Low Energy, and this has allowed the developers of the Agent Smartwatch to add support for this new technology to the emulator that is currently available.
Developers with Windows 8.1 on their development PCs will be able to build and test apps which interact with low-energy sensors like temperature sensors and heart rate monitors.
An SDK for Windows 8 Metro apps will also be released, which will allow developers to create Windows 8 companion apps for the watch easily.
Windows Phone 8 does not support Bluetooth Low Energy yet, but the developers are hoping support will come in the next major version of the OS.
In the interim this means the Agent Smartwatch will be able to act as a bridge of sorts, allowing access to Bluetooth LE gadgets like the Fitbit, and then presenting the data using Bluetooth 3.0 to Windows Phones.
The Agent SmartWatch project is progressing well at present, with production circuit boards (above) currently in testing, which should after a few rounds of revisions turn into a final design which can enter production.
Hopefully this means by the time the Apple iWatch comes out Windows Phone users will also be able to join in the fun.
