Bluetooth SIG announces Bluetooth 4.2, targets IoT
Bluetooth 4.2 boasts improved privacy, higher speed, and a profile that will be ratified in the near future that 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.”
Bluetooth 4.2 has enhanced security features that not only offer greater protection to the consumer that build upon the government-grade security features of the earlier Bluetooth specification, but also enable lower power consumption.
The latest 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.
By increasing the capacity of Bluetooth Smart packets, devices using Bluetooth 4.2 can now 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.
The soon to be ratified 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.
