ARM seeks energy harvesting edge in IoT push, buys Bluetooth companies

April 16, 2015 // By Paul Buckley
With battery lifetimes becoming an increasing preoccupation of some of the world's largest brands including Google, Apple, Tesla and Dyson it now seems UK-based ARM is focusing on extending the battery life of sensors using Bluetooth to address the IoT.

This week ARM has snapped up Wicentric, a Bluetooth Smart stack and profile provider, and Sunrise Micro Devices (SMD), a provider of sub-one volt Bluetooth radio intellectual property (IP).

The IP of both Wicentric and SMD will be integrated to form the ARM Cordio portfolio which is aiming to complement ARM’s existing processor and physical IP targeting end markets requiring low-power wireless communications such as the Internet of Things (IoT).  ARM is keen to make the Cordio solutions efficient enough to be powered using energy harvesting and sees SMD's sub-one volt Bluetooth radio IP as a vital ingredient in the design armoury.

SMD is a privately held provider of radio IP solutions including a pre-qualified, self-contained radio block and related firmware to simplify radio deployment. Central to all SMD radios is native sub-one volt operation.  Wicentric is also a privately held provider of Bluetooth Smart software solutions focused on enabling the development of low-power wireless products. The company's product line includes Bluetooth protocol stack and profiles for creating interoperable smart products and the link layer for silicon integration.
