Tiny Bluetooth low energy proximity key fob runs for a year on a coin cell
June 13, 2012 // Jean-Pierre Joosting
Nordic Semiconductor ASA has announced that Hong Kong-headquartered Dayton Industrial Co. Ltd., a leading OEM/ODM of wireless products has launched a Bluetooth® low energy proximity key fob based on Nordic's µBlue™ nRF8002 System-on-Chip (SoC) that is less than half the size of a credit card.
The Dayton production-ready product platform will allow OEMs and developers to develop a whole range of both standard (Bluetooth v4.0 profile-based) and non-standard (uniquely developed) proximity, property location and security applications ('apps') for use with devices that employ Bluetooth v4.0 wireless technology such as the latest iPad and the iPhone 4S.
The nRF8002s ULP design features peak currents as low as 13 mA and does not require an external 32 kHz crystal. Depending on the duty cycle of the application, battery life from a single coin cell-powered wireless device can extend to months or even years.
Within the latest Bluetooth v4.0 specification there are currently two profiles applicable to proximity-based property location and security. The first, the Find Me profile targets smartphone applications and allows users to pair small but commonly misplaced everyday objects with their smartphone in order to locate them via, for example, a Bluetooth low energy proximity key fob that could be used to find a misplaced phone (by pushing a button on the fob to make the phone sound an audible alert), or a misplaced key fob (by pushing a button within a smartphone app to make the key fob sound an alert).All news
