STMicroelectronics SPBTLE-RF Bluetooth Chip 4.1

The SPBTLE-RF is an easy ready-to-use Bluetooth v4.1 compliant. This Smart master/slave mode network processor module supports multiple roles simultaneously. It can act at the same time as Bluetooth Smart sensor and hub device.
The entire Bluetooth Smart stack and protocols are embedded into SPBTLE-RF B-SmarT module. A standard SPI interface establishes the communication with an external host microcontroller.
The SPBTLE-RF can be powered directly with a standard 3 V coin cell battery.
