Bluetooth 4.2 allows IP connectivity for devices

The Bluetooth Special Interest Group (SIG) has introduced the Bluetooth 4.2 version. The next-gen Bluetooth protocol brings IP connectivity to smart devices, as well as delivers faster data transfer and better privacy.

Bluetooth 4.2 builds upon the government-grade security features of the Bluetooth specification. Its 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 will reduce transmission errors, therefore leading to lower battery consumption.

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.

Twelve Bluetooth SIG member companies that worked together to develop the recent Bluetooth include Anritsu, Apple, Broadcom, CSR, Intel, IVT Corp., Nordic, Qualcomm Atheros, RivieraWaves, Samsung, Sunrise Micro Devices and Wicentric.
