Get Heart Rate from BLE Device on Windows 8?

Hi,

I am developing a game that receives the player's heart rate from a Mio Alpha Watch using Bluetooth Low Energy (BLE). I managed to find a plugin that works on Mac, iOS and Android but no Windows support. My question is, is there a plugin available to connect with Windows? Because I searched through the whole assets store with no luck. I would really appreciate someone pointing a way for me to get that to work or providing me with another solution. I am all ears!

I also tried looking for ANT+ devices but that seems to require me to build a plugin, unless I could find a ready plugin or a tutorial that will help me to build it and integrate it with Unity3D.

Many thanks!
