A better Bluetooth

As we approach an era that will be dominated by the Internet of Things (IoT), the Bluetooth Special Interest Group (SIG) announced the new Bluetooth 4.2 specification with several promising new features and updates. It comes a year after SIG certified Bluetooth 4.1, and with this latest update, Bluetooth sees improvements in several different areas, including a new direct Internet access feature.
"Bluetooth 4.2 is all about continuing to make Bluetooth Smart the best solution to connect all the technology in your life – from personal sensors to your connected home. In addition to the improvements to the specification itself, a new profile known as IPSP enables IPv6 for Bluetooth, opening entirely new doors for device connectivity," said Mark Powell, executive director of the Bluetooth SIG. "Bluetooth Smart is the only technology that can scale with the market, provide developers the flexibility to innovate, and be the foundation for the IoT."
It's also a faster spec -- by increasing the capacity of Bluetooth Smart packets, devices can transfer data up to 2.5 times faster than with previous versions, according to SIG. This will also result in fewer transmission errors and longer battery life for Bluetooth devices.
Privacy is the other big feature upgrade in Bluetooth 4.2. New privacy features protect mobile users from being tracked through their Bluetooth gadget. That means if you enter a store with beacons, they won't be able to engage with and track your Bluetooth device unless you've enabled permission.
