Bluetooth low energy and its predecessors have been in the pipe for ages now, but we might actually see this technology finally take off en masse for the first time now that the Bluetooth SIG has officially added it into a release: 4.0.
While Bluetooth 3.0 was all about high energy with the introduction of WiFi transfer, Bluetooth 4.0 takes things down a notch by certifying single-mode low energy devices in addition to dual-mode devices that incorporate both the low energy side of the spec plus either 2.1+EDR or 3.0.
Although Bluetooth 3.0 has been out for a while, you don’t see any Bluetooth 3.0 specs on Bluetooth products. I wonder how many Bluetooth products out there have already adopted Bluetooth 3.0? I wish manufacturers would list which Bluetooth version they have implemented along with the type of Audio profile for headsets and speakers as this always is a real lottery trying to work out if a product is going to be any good or just a flop.
