The Bluetooth SIG recently announced the Bluetooth 4.2 core technology standard. The new technology can enhance privacy protection, speed up data transmission, and enable devices to access the Internet via Bluetooth. The new standard allows Bluetooth to be used over IPv6, which means that devices can connect directly to the Internet, which opens up new possibilities for Bluetooth sensors and other peripherals.
Mark Powell, executive director of the Bluetooth Technology Alliance, said: "Bluetooth 4.2 continues to make smart Bluetooth the best solution for connecting all the technologies in life - from personal sensors to connected homes. In addition to improving standards, the new IPSP profile opens IPv6 for Bluetooth. Features."
For privacy, the new privacy features of the new Bluetooth 4.2 standard make it difficult for users to track through Bluetooth devices. The new standard of privacy technology makes the Bluetooth Smart Location Tracker accessible only to owners and trusted people. The Bluetooth Technology Alliance also mentioned that the new standard is more efficient and includes FIPS encryption to create secure connections. Finally, Bluetooth 4.2 requires only a firmware upgrade to increase speed by a factor of 2.5.
With Bluetooth 4.2, smart bulbs, thermostats, and sensor doors can be used to connect directly to the Internet without using other intermediate devices, which will greatly promote the intelligent process of furniture. The Bluetooth SIG said that new technologies will be widely used in the market, making Bluetooth 4.2 the cornerstone of IoT operations.
At the same time, the new version is better able to ensure that the device is not being tracked. For example, Apple iBeacons (low-power Bluetooth transmission devices) that use Bluetooth 4.2 will not track any traces of iBeacons unless they are allowed to connect with other devices. In addition, Bluetooth 4.2 consumes less power and delivers more than twice the speed of earlier versions.
A Bluetooth SIG spokesperson said that many devices are now equipped with Bluetooth 4.0, although the old device can be used with Bluetooth 4.1 before the software upgrade, but this time not all new features can run on the old device, to experience the new The version is light and fast and must use the latest equipment.
The latest collection of Bluetooth smart technology data, please pay attention to this week's Designs of week - let your smart Bluetooth product design no longer be resigned!
With the continuous development of technology, wireless network has become an indispensable part of our daily life. The router WiFi module is an important part of the wireless network. In this article, we will introduce the router WiFi module in detail.
