Korean manufacturer Semilink has developed a Bluetooth low energy proximity key fob based on Nordic Semiconductor’s μBlue nRF8002 system-on-chip (SoC).
Called the 'Pebble', the key fob offers two functions that build on the two profiles defined in the latest Bluetooth v4.0 Specification applicable to proximity-based property location and security.
The Proximity profile ensures that when the key fob moves out of range of the smartphone or tablet computer to which it is wirelessly connected, the user is alerted by an audible alarm, eliminating the risk of leaving valuable devices behind.
Alternatively, the user is warned by the key fob if an unauthorised person moves the valuable portable device out of range. The Find Me profile enables a misplaced key fob to be located by triggering an alarm from a dedicated application on the portable device. This is useful if the key fob is attached to a set of keys or other valuable possession.
Pebble features an ultra-slim design, measuring just 60 by 30 by 11 mm and weighing in at less than 12 grams. Powered by a regular 3 V CR2025 lithium coin cell, the nRF8002’s low power consumption extends battery life to over a year under typical (daily) usage conditions. The device’s range is typically around 10 metres but can extend up to 20 metres.
