Finally the specification of the next "Bluetooth 4.2" obviously became faster and more secure IPv6 is also supported

Keyboards and headphones that can be used wirelessly via Bluetooth are becoming common, but oversee the development of the Bluetooth standardBluetooth SIGIs officially "Bluetooth 4.2"We announced that it adopted. Detailed specifications are released on how to evolve from old standards such as Bluetooth 4.0 (Bluetooth LE).

◆ Full control of Internet connection


It is the latest version internet protocolIPv6/6LoWPANviaBluetooth SmartYou can now access the device, from the beginning of 2015Generic Attribute Profile (GATT)Attribute Bluetooth Smart device will be able to connect directly to the Internet.


Examination of Harvard Business ReviewAccording to the forecast that it will exceed 28 billion by 2020Internet of things"It will become even more power-efficient and comfortable to use.

◆ Improved speed and safety


Communication is protected by government-class security, and even if you use a beacon on a Bluetooth Smart device, for example, it will not be monitored or tracked without permission.


With respect to speed, Bluetooth Smart packet has become ten times faster, achieving 2.5 times faster than conventional transfer rate. As a result, transmission error is reduced and power saving connection is enabled.

Incidentally,According to the information that Ars Technica heard from representatives of Bluetooth SIG, The privacy function of Bluetooth 4.2 may be applicable also to older Bluetooth adapters due to firmware update by each manufacturer, but as for the speeding up of transfer rate and packet increase, if the latest version of hardware is needed It is. Although Bluetooth SIG is going to verify the adapter of the old version of Bluetooth standard, probably it does not seem to be able to fully demonstrate the specification of Bluetooth 4.2 with the hardware compatible with the old version.
