Introduction

The BlueNRG-MS is a very low power Bluetooth low energy (BLE) single-mode network processor, compliant with Bluetooth specification v4.2. The BlueNRG-MS supports multiple roles simultaneously and can act at the same time as Bluetooth smart sensor and hub device. The Bluetooth Low Energy stack runs on the embedded ARM Cortex-M0 core. The stack is stored on the on-chip non-volatile Flash memory and can be easily upgraded via SPI. The device comes pre-programmed with a production-ready stack image. A different or more up-to-date stack image can be downloaded from the ST website and programmed on the device through the ST provided software tools. The BlueNRG-MS allows applications to meet the tight advisable peak current requirements imposed by standard coin cell batteries. The maximum peak current is only 10 mA at 1 dBm output power. Ultra low-power sleep modes and very short transition times between operating modes allow very low average current consumption, resulting in longer battery life. The BlueNRG-MS offers the option of interfacing with external microcontrollers via SPI transport layer.

The BlueNRG-MS is a single-mode Bluetooth low energy master/slave network processor, compliant with the Bluetooth specification v4.2. It integrates a 2.4 GHz RF transceiver and a powerful Cortex-M0 microcontroller, on which a complete power-optimized stack for Bluetooth single mode protocol runs, providing: Master, slave role support GAP: central, peripheral, observer or broadcaster roles ATT/GATT: client and server SM: privacy, authentication and authorization L2CAP Link Layer: AES-128 encryption and decryption An on-chip non-volatile Flash memory allows on-field Bluetooth low energy stack upgrade. In addition, according the Bluetooth specification v4.2 the BlueNRG-MS can support the following features through firmware updates: Multiple roles simultaneously support Support simultaneous advertising and scanning Support being slave of up to two masters simultaneously Privacy V1.1 Low duty cycle directed advertising The device allows applications to meet of the tight advisable peak current requirements imposed with the use of standard coin cell batteries. If the high efficiency embedded DC-DC step-down converter is used, the maximum input current is only 15 mA at the highest output power (+8 dBm). Even if the DC-DC converter is not used, the maximum input current is only 29 mA at the highest output power, still preserving battery life. Ultra low-power sleep modes and very short transition time between operating modes result in very low average current consumption during real operating conditions, providing very long battery life. Two different external matching networks are suggested: standard mode (TX output power up to +5 dBm) and high power mode (TX output power up to +8 dBm). The external host application processor, where the application resides, is interfaced with the BlueNRG-MS through an application controller interface protocol which is based on a standard SPI interface.
