The first such device is a Dayton heart-rate chest strap using a Bluetooth 4.0 chip from Nordic Semiconductor. Foley envisions that gyms and fitness centers would have Bluetooth-enabled computers so that you could automatically upload your fitness stats to the cloud after you finish your workout, for example. This version of Bluetooth is thus targeted specifically for small battery-operated devices like Nike+ sensors, Fitbits, and similar products that require almost no power. "It enables an entirely new class of product into the Bluetooth world." "It's an extremely optimized version of Bluetooth," Foley said. If these same devices had Bluetooth 4.0, they could speak to any Bluetooth 4.0 device, be it phone or computer, without requiring an intermediary.


Most pedometers, heart rate straps, and blood glucose monitors are designed to only talk to a specific wristwatch or control unit. An obvious example is in the health and fitness category. This lets device manufacturers replace proprietary sensor technology with Bluetooth, which is a more widely adopted standard. The Apple iPhone 4S is the first phone to ship with Bluetooth 4.0.Īccording to Mike Foley, executive director of the Bluetooth SIG (Special Interest Group), the key new feature of Bluetooth 4.0 is its low-energy technology. Bluetooth 4.0 is backward-compatible with all other versions of Bluetooth, so you can pair existing Bluetooth headsets with the new iPhone without a problem. Not many products are available with Bluetooth 4.0 just yet-in fact, two of the most recent products to ship with Bluetooth 4.0 are also from Apple: the MacBook Air and the Mac Mini. One of the lesser-known facts to emerge about the iPhone 4S yesterday is that it is the first phone to launch with Bluetooth 4.0, the latest version of Bluetooth.
