"Google Edition" of HTC One, running Android 4.3., visits Bluetooth SIG
So why would a device already approved for Bluetooth need to go through the whole certification process again? It could simply be due to the Android 4.3 update which will add Bluetooth 4.0 LE support. This is the Low Energy version of Bluetooth that allows a phone to sync with accessories like heart rate monitors, thermometers and other similar monitors.
Keep in mind that Android 4.3 has not been officially announced by Google, but we could see it rolled out sometime later this month for Google Edition and Nexus devices with a possible refresh version of the Google Nexus 7 tablet, recently seen by the FCC, also getting unveiled.
