Bluetooth Version 4.2 Features

After Bluetooth version 4 which is more having a quick integration without have to pair with another device, Bluetooth keeps improving the version. It’s improving their performance and features in the newest level. Bluetooth Special Interest Group has ratified a new version of the Bluetooth Low Energy standard (which the SIG calls Bluetooth Smart) that adds new security features preventing people from sniffing out your Bluetooth signal and using it to track your phone and devices as you move about.

We can say that the new version of Bluetooth Smart is more secure. You don’t have to worry about your phone is being tracked and you will get some more privacy. The new version of the standard, called Bluetooth 4.2, essentially hides the media access control (MAC) address every Bluetooth devices uses as an identifier.

The feature is optional, so devices that are intended to broadcast their identities for authentication and location purposes — beacons, for instance — can share their IDs freely. But if you’re just wandering around with a smartphone or activity tracker, you won’t have to worry about devices you haven’t authorized using your MAC address to keep tabs on you.

The 4.2 specification contains other updates as well, but they mainly extend classic Bluetooth features ratified last year in the 4.1 standard to Bluetooth Low Energy. The SIG claims, for instance, that BLE is getting a speed boost, though the organization refused to provide any specific numbers. With 4.2 also comes a new Bluetooth profile the SIG promised last year that will allow BLE sensors and devices to connect directly to the internet of things with an IPv6 address.

This will widen the improvement of Internet of Things. Everyone can work with Bluetooth Smart or Bluetooth V2. Beside it does not need to be paired, Bluetooth Smart is also secure. It won’t let anyone track your bluetooth signal and track your activities. Turning on your bluetooth will not risk somebody spying on you.
