ST BlueNRG－MS低功耗蓝牙(BLE)单模式网络处理方案

ST公司的BlueNRG-MS是低功耗蓝牙(BLE)单模式网络处理器,嵌入Cortex M0核,和蓝牙v4.1标准兼容,嵌入了低功耗蓝牙协议堆栈GAP, GATT, SM, L2CAP, LL和RF-PHY,工作电压1.7v-3.6v,最大发送电流8.2Ma(@0 dBm, 3.0 V),主要用在手表,健身,健美和运动,消费类医疗设备,遥控,家庭和工业自动化,手机外设,PC外设,安防和资产管理.本文介绍了BlueNRG-MS主要特性,功能框图和多种应用电路,以及低功耗蓝牙评估板X-NUCLEO-IDB04A1主要特性,电路图和材料清单.
The BlueNRG-MS is a very low power Bluetooth low energy (BLE) single-mode networkprocessor, compliant with Bluetooth specification v4.1. The BlueNRG-MS supports multipleroles simultaneously, and can act at the same time as Bluetooth Smart sensor and hubdevice.
The entire Bluetooth low energy stack runs on the embedded Cortex M0 core. The nonvolatile Flash memory allows on-field stack upgrading. The BlueNRG-MS allowsapplications to meet of the tight advisable peak current requirements imposed with the useof standard coin cell batteries. The maximum peak current is only 10 mA at 1 dBm of outputpower. Ultra low-power sleep modes and very short transition times between operatingmodes allow very low average current consumption, resulting in longer battery life. TheBlueNRG-MS offers the option of interfacing with external microcontrollers using SPItransport layer.
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 ...
