Product Overview

The BLE112 is a Bluetooth Smart module targeted for low-power sensors and accessories. It integrates all features required for a Bluetooth Smart application, including Bluetooth radio, software stack, and GATT-based profiles. The BLE112 Bluetooth Smart module can also host end-user applications, which means no external micro controller is required in size or price constrained devices. Morover, ithas flexible hardware interfaces to connect to different peripherals and sensors and can be powered directly from a standard 3V coin cell battery or a pair of AAA batteries. In the lowest power sleep mode it merely consumes 500 nA and will wake up within a few hundred microseconds.
