The BLUENRG-MSQTR is a very low power Bluetooth low energy (BLE) single-mode network processor, compliant with Bluetooth specification v4.2. The BLUENRG-MSQTR supports multiple roles simultaneously and can act at the same time as Bluetooth smart sensor and hub device.
The Bluetooth Low Energy stack runs on the embedded ARM Cortex-M0 core. The stack is stored on the on-chip non-volatile Flash memory and can be easily upgraded via SPI.
The device comes pre-programmed with a production-ready stack image(Its version could change at any time without notice). A different or more up-to-date stack image can be downloaded from the ST website and programmed on the device through the ST provided software tools.
The BLUENRG-MSQTR allows applications to meet the tight advisable peak current requirements imposed by standard coin cell batteries.
The maximum peak current is only 10 mA at 1 dBm output power. Ultra low-power sleep modes and very short transition times between operating modes allow very low average current consumption, resulting in longer battery life.
The BLUENRG-MSQTR offers the option of interfacing with external microcontrollers via SPI transport layer.
