The Bluetooth SIG has just announced that it has officially adopted the Bluetooth Core Specification Version 4.0. Low energy consumption is just one of the major improvements of v4.0 over the v3.0.
Having made that step, the Bluetooth SIG (short for Bluetooth Special Interest Group) is now ready to start qualifying all sorts of Bluetooth products to the version 4.0 specification and first devices with Bluetooth 4.0 support are expected to show up before this year ends.
The upcoming Bluetooth version will be optimized for low power battery operation which will help the technology to conquer new markets such as health care, fitness and sports where devices require low power and low cost wireless connectivity.
Lower power consumption will also allow the technology to be used in way smaller products than before such as tiny coin-cell battery powered devices and sensors. According to the Bluetooth SIG, thanks to the decreased demand for power, products will be able to run for years on standard coin-cell batteries.
The other improvements brought to Bluetooth by v4.0 include low cost, multi-vendor interoperability and enhanced range.
Well, i think that Bluetooth 3 wasn't successful due to his hi energy consumption compared to v.2.1 So if they've solve the problem why it won't be used widely? what I'd like to know is the difference between v.2.1 and v.4 in energy consumption?...
and calling a device "magical" isn't?
...because "awesomely small" sounds unprofessional.
