Technical information:Technical information:
Wibree isnt designed to replace Bluetooth,but to complement the
supported devices.
Wibree-enabled devices are smaller
And energy-efficient than Bluetooth.
Replacing Bluetooth with Wibree will makethe devices closer in
dimensions and weightto current wristwatches.
