The Bluetooth Special Interest Group (SIG) has officially adopted version 4.2 of the Bluetooth core specification. Key updates in 4.2 improve privacy and increase speed, and a soon-to-be ratified profile will enable IP connectivity.

“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.”

Privacy and Security
Bluetooth 4.2 introduces industry-leading privacy settings that lowers power consumption and builds upon the government-grade security features of the Bluetooth specification. The new privacy features put control back into the hands of the consumer by making it difficult for eavesdroppers to track a device through its Bluetooth connection without permission. For example, when shopping in a retail store with beacons, unless you’ve enabled permission for the beacon to engage with your device, you can’t be tracked.

Bluetooth 4.2 increases the speed and reliability of data transfers between Bluetooth Smart devices. By increasing the capacity of Bluetooth Smart packets, devices transfer data up to 2.5 times faster than with previous versions. Increased data transfer speeds and packet capacity reduces the opportunity for transmission errors to occur and reduces battery consumption, resulting in a more efficient connection.

Internet Connectivity
Building on the capabilities released earlier with Bluetooth 4.1 and the new features released in 4.2, the Internet Protocol Support Profile (IPSP) will allow Bluetooth Smart sensors to access the Internet directly via IPv6/6LoWPAN. IP connectivity makes it possible to use existing IP infrastructure to manage Bluetooth Smart “edge” devices. This is ideal for connected home scenarios that need both personal and wide area control. This profile will be ratified by the end of the year.

We'll have to wait a while before manufacturers release devices based on the Bluetooth 4.2 spec. Until then, hit the link below for more details!

This is one great thing about Android device makers, they are quicker at including newer tech in their devices. This is likely to make it to Apple's next line of Macs.

Yes but ther needs to be more in it to be as good as ios. Better Bluetooth is no exception.
