Google's announced a new Bluetooth tweak called “Fast Pair”.
The tech is conceptually simple: an Android device Bluetooth Low Energy (BLE) gets the job of advertising and discovery, then ye olde Bluetooth handles pairing.
The guts of it are of course more complicated.
For starters, Bluetooth devices need to be built to run Fast Pair.
Android devices need to have Bluetooth and location services turned on.
A trip to Google's cloud is required, too, as the company says that once BLE finds a Fast Pair packet “is sent to our servers to get back the device's product image, product name and companion app (if there is one).”
