Overview
The BlueNRG-MS, specifically the BLUENRGCSP model from STMicroelectronics, is a highly efficient Bluetooth Low Energy (BLE) single-mode network processor. It is compliant with the Bluetooth specification v4.2 and supports multiple roles simultaneously, acting as both a Bluetooth smart sensor and a hub device. The device features an embedded ARM Cortex-M0 core, which runs the Bluetooth Low Energy stack stored in on-chip non-volatile Flash memory. This allows for easy upgrades via SPI. The BlueNRG-MS is designed to meet the stringent power requirements of coin cell batteries, with ultra-low power sleep modes and short transition times between operating modes, resulting in extended battery life.
