The Bluetooth Special Interest Group (SIG) today announced the new Bluetooth 4.2 specification, which promises enhanced privacy measures, increased speed of data transfers, and an update that will allow Bluetooth Smart sensors to directly access the Internet.
The group emphasizes connected home scenarios as being able to take the most advantage of Bluetooth 4.2's new direct Internet access feature, promising low-power connectivity using the standard and with IPv6 support available by year's end.
“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.”
The new 4.2 spec also promises speedier data transfers between devices, up to 2.5 times faster than previous versions. Bluetooth SIG promises that "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."
The new privacy features also take aim at lowering power consumption, while protecting consumers from being tracked through their Bluetooth devices. As more retail stores and public places accept Bluetooth beacons and similar applications, Bluetooth SIG hopes to be at the forefront for protecting every user's personal and private information.
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.
The standard Bluetooth 4.2 specification is available now, with the new direct Internet access feature due within a month.
