STMicroelectronics has released the latest version of its award-winning BlueNRG Bluetooth® SMART network processor, which supports the latest Bluetooth version 4.1 enhancements and operates from a 1.7V power supply for longer lasting battery-powered applications.

The new BlueNRG-MS network processor integrates a complete Bluetooth PHY and 2.4GHz radio, ARM® Cortex®-M0 MCU running the Bluetooth 4.1 protocol stack, and a dedicated AES-128 security co-processor. The device also includes an application programming interface, power-management unit and Flash memory, allowing direct connection to the application’s host controller using a simple SPI bus.

By implementing the new Bluetooth 4.1 specification, the BlueNRG-MS enables developers to achieve improvements in energy efficiency while supporting dual-mode topologies containing devices operating as both master and slave.

The new Low-Duty-Cycle Directed Advertising mode minimises power consumed when connecting to known devices. In addition, Bluetooth 4.1 introduces the Logical Link Control and Adaptation Protocol (L2CAP), which enables flexible data exchanges to take advantage of multi-channel communications and improved quality of service.

ST’s BlueNRG-MS network processor can power devices such as a hub capable of collecting sensor data and subsequently acting as a peripheral to transfer the data to a smart phone. It can also enable the development of very large sensor networks with unlimited communication range, controlled by a single smartphone. Moreover, BlueNRG-MS supports the latest moves towards IP-based connectivity in Bluetooth 4.1, which enables developers to cater for future IoT opportunities.
