The new Bluetooth 4.2 specification aims to assist small Bluetooth powered devices in easily connecting to the world wide web. This standard could usher in a new wave of cost effective, web ready Internet of Things devices.
Currently, Bluetooth devices are often dependent on another host device for their internet access, be that your smartphone, computer or some other hub. This isn’t ideal if you want the device to grab data from the internet for itself. Bluetooth 4.2 allows for a direct connection to internet routers and hot-spots using low-power IPv6/6LoWPAN protocols. This could prove hugely beneficial for small, low-power IoT devices and home automation, as well as the next generation of wearables.
Bluetooth 4.2 also aims to tackle issues of privacy and improved data speeds. Other devices should find it harder to track 4.2 versions without the correct permissions. Data speeds are also looking at a potential boost of 250 percent and a 10 fold packet capacity increase. General power efficiency is also set for an improvement.
The standard is already complete and waiting for manufacturers and developers to make use of it. Direct internet access capability expected to be ready before the year’s end. Bluetooth 4.2 devices will likely begin to appear sometime in early/mid 2015.
