Chrome Bluetooth Low Energy API - Cross-Platform Support

I accessed the Chrome BLE API page (5/7/2016). there seem to be conflicting information messages (see image below). Does this work on Chrome OS only, or OS X and Windows also?

EDIT/UPDATE:

I tried the demo application (demo BLE API) on Windows 10. It was able to see paired devices, but not unpaired devices. I got an error message: Battery device not supported on this platform. I'm not sure if this is because of the test vector I used (LightBlue), or another issue.

System:

The chrome.bluetoothLowEnergy API works only for paired devices on Windows as it still uses (at that time) Windows 8 APIs to retrieve paired devices only: https://chromium.googlesource.com/chromium/src/+/08c9d69b0c0d625d2ce38e3d8402f36e1226f0fc/device/bluetooth/bluetooth_low_energy_win.h#117

For info, the Web Bluetooth team plans to support Windows 10 as much as feasible: https://github.com/WebBluetoothCG/web-bluetooth/blob/gh-pages/implementation-status.md#chrome

Reading through your given documentation wherein you referenced the use of navigator.bluetooth, Interact with BLE devices on the Web also states that:

Web Bluetooth API is at the time of writing partially implemented in Chrome OS and Chrome Dev for Android behind an experimental flag.

Hence, you got undefined as a return value.

Functionalities were provided by Bluetooth Low Energy (BLE) through key/value pairs provided by the Generic Attribute Profile (GATT).
