Bluetooth Special Interest Group (SIG) has officially announced Bluetooth 4.2 which brings improved security, increased speed, and IP connectivity to the wireless technology standard.
Bluetooth 4.2 key features:
• Privacy and Security – 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 makes it difficult for eavesdroppers to track a device through its Bluetooth connection without user permission.
• Speed and Capacity- transfer speeds is now 2.5 times faster while packet capacity is 10 times more versus previous versions. This reduces transmission errors for lower battery consumption and more efficient connection.
• Internet Connectivity – Bluetooth 4.2 brings Internet Protocol Support Profile (IPSP) to allow Bluetooth Smart sensors to access the Internet directly via IPv6/6LoWPAN.
Certain features like enhanced privacy and security can be implemented to some older Bluetooth 4.x adapters via firmware update. However, increased transfer speeds and capacity will require newer hardware.
