Is Android Wear device used Bluetooth to connect to Android Phone device over the air?

Question

Followed Android Wear GUIDE .

People noted this :

The Android Wear Preview app is compatible with Android 4.3 and higher and is not available for the Android emulator.

This thing may be indicated that it will use Bluetooth Low Energy - BLE, to establish connection between Android Wear device - Wrist Watch, and Android mobile devices since BLE technology only be available on Android 4.3 or higher, and not available on Android Emulator . But I am not sure.

Currently I know this to connect Android Wear Emulator with Android Phone device :

Connect your device to your development machine over USB .

But I wonder that when Wrist Watch device with real Android Wear SDK was released,

It will be used what's thing to connect to Android Mobile device?

Please tell me,

Thanks,

p/s : If I am right, it also means the Android Mobile devices can connect to Wrist Watch will be limited since not most of Android Mobile devices always support BLE technology.

Answer 1

Long story short: No-one knows for sure.

Long story long: Your observations point to BLE, and looking at the emulator we can also find pieces of information pointing to a bluetooth-based connection.

But until Google releases more information on how things are going to be, we cannot say anything for sure yet.
