The Bluetooth Special Interest Group (SIG) has officially announced the adoption of Bluetooth 4.2. The new specification provides privacy, security, speed, and reliability improvements, with data transfer rates up to 2.5 times faster than previous versions, and reduced battery consumption. The new specification also includes an upcoming Internet Protocol Smart Profile (IPSP), expected to be ratified by year-end, which will extend Bluetooth to provide direct Internet access capabilities for smart devices via IPv6, allowing existing network infrastructure to be used to manage Bluetooth Smart devices rather than relying on proprietary protocols and gateway devices.
