6 / 42 page ![]() General description BlueNRG-MS 2 General description The BlueNRG-MS is a single-mode Bluetooth low energy master/slave network processor, compliant with the Bluetooth specification v4.1. 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 v4.1 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. 6/42 DocID027103 Rev 6 |
