Connect Internet through Bluetooth 4.2 Update

The Bluetooth Special Interest Group (SIG) officially adopted version 4.2 of the Bluetooth core specification this week. Key updates in 4.2 improve privacy and increase speed, and a soon-to-be ratified profile will enable IP connectivity. Bluetooth 4.2 opens up new opportunities for developers, OEMs and the industry to build a better user experience for consumers while creating use cases never before imagined.

“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.” 

Speed
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 reduces the opportunity for transmission errors to occur and reduces battery consumption, resulting in a more efficient connection. 

Internet Connectivity
Building on the capabilities released earlier with Bluetooth 4.1 and the new features released in 4.2, 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.

Wireless Technology

Bluetooth wireless technology is the global wireless standard enabling simple, secure connectivity for an expanding range of devices and serves as the backbone of the connected world. Bluetooth Smart technology, through an updatable platform and low power consumption, creates new application opportunities for the mobile phone, consumer electronics, PC, automotive, health & fitness and smart home industries. With nearly three billion devices shipping annually, Bluetooth is the wireless technology of choice for developers, product manufacturers, and consumers worldwide. Backed by industry leading companies, the Bluetooth SIG empowers over 24,000 member companies to collaborate, innovate and guide Bluetooth wireless technology.

Bluetooth^® Core Specification 4.2

Bluetooth® Core Specification 4.2 is an important update to the Bluetooth Core Specification delivering exciting new features and benefits for Bluetooth Smart. This will create significant advantages for developers and manufacturers, while providing a better user experience for their customers. Bluetooth 4.2 makes Bluetooth Smart even smarter, faster and the ideal wireless technology for the Internet of Things (IoT).
