Bluetooth low energy – the Momentum Builds

It’s been a good week for Bluetooth low energy.  At times it’s felt like a long, slow path since it was first announced as Wibree in October 2006, but that feeling is changing as the standard is coming to completion.  This week saw the first Bluetooth low energy conference take place in Munich where chips vendors were showing off demos, whilst on the other side of the world, at the ARM Techcon in Santa Clara, there were more live demonstrations of the technology.

The mood of the industry has become increasingly upbeat.  It was noticeable in Munich that a significant number of companies have moved from cautious interest to being serious about starting to deploy it.  The questions that they are asking have changed to the practical ones of qualification and access to test equipment.  That change in mood was reinforced by the Bluetooth SIG announcing that the specification is on course to be released this December.

The Bluetooth low energy standard can be confusing at first.  Although it carries the name Bluetooth, it is a completely new radio with a completely new protocol stack on top of it.   It has been designed from scratch to allow developers to add connectivity to products that only want to send small pieces of data on an irregular basis, but with such low power consumption that it can run on coin cells.  The companies attending the Conference in Munich have understood that difference and are keen to exploit the new products and service models that Bluetooth low energy offers.
