STMicroelectronics BlueNRG-MS Bluetooth Smart Network Processors
STMicroelectronics BlueNRG-MS BLUETOOTH® Smart Network Processors have a low current consumption for coin cell battery-powered smart device applications. These processors are ideal for Bluetooth applications that need to operate for months or even years. The BlueNRG-MS run embedded Bluetooth low energy protocol stacks GAP, GATT, SM, L2CAP, LL, and RF-PHY on an embedded Cortex®-M0 core. The BlueNRG-MS are connected through a proprietary SPI-based interface to a host MCU running the application.
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.
