STMicroelectronics BlueNRG-MS 蓝牙智能网络处理器

STMicroelectronics BlueNRG-MS Bluetooth® 智能网络处理器电流消耗低，用于钮扣电池供电的智能设备应用。这些处理器非常适用于需要运行数月甚至数年的蓝牙应用。 BlueNRG-MS 运行嵌入式蓝牙低功耗协议栈 GAP、GATT、SM、L2CAP、LL 和嵌入式 Cortex®-M0 内核上的 RF-PHY。 BlueNRG-MS 通过基于 SPI 的专有接口连接至运行该应用程序的主机 MCU。

The BlueNRG-MS supports master and slave roles and can operate as central (managing up to 8 peripherals) or peripheral device without any change in the firmware. The Bluetooth profiles are provided separately and meant to run in the host MCU.
