Overview
The BlueNRG-MS, specifically the BLUENRGQTR model from STMicroelectronics, is a very low power 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 integrates an ARM Cortex-M0 microcontroller core and a complete power-optimized BLE stack, which is stored on the on-chip non-volatile Flash memory and can be easily upgraded via SPI.
