“Bluetooth 4.2 makes tracking more difficult, and facilitates the data transfer of 2.5 times faster”

The Bluetooth Special Interest Group has the specifications of bluetooth 4.2 be determined and posted online. In the new version, switch devices, each of mac address, allowing the tracking of users via bluetooth tracking a lot harder.

Thanks to the change of mac address can devices a smartphone not continue to recognize it, because now look at the mac address. Also, beacons in, for example, stores devices, only to wake for more of the messages as, for example, users of the app store on their device; the software keeps a whitelist in bluetooth 4.2. Because beacons smartphones less often of interest, this feature should the battery usage of bluetooth on smart phones reduce.

In addition, the new bluetooth version is 2.5 times faster at data transfer than bluetooth 4.1. In addition, there should be fewer errors in data transfer to take place. In addition, it supports bluetooth, the new version has a direct connection via ipv6, which is particularly useful in small engines that the ‘internet of things’ shapes. For the internet is, of course, does require a network connection via a router or set-top box with bluetooth, but this is the internet-of-things-devices do not need wi-fi on board.

A feature that is missing in bluetooth 4.2 is the ability to use various bluetooth devices to a mesh network to build. The members of the Bluetooth SIG are working on it, says a top executive at EETimes. “It is a clear priority.”
