FP-SNS-ALLMEMS2 is an STM32Cube function pack which lets you connect your IoT node to a smartphone via BLE and use a suitable Android™ or iOS™ application, like the BlueMS app, to view real-time environmental and motion sensor data, digital microphone and battery levels.
It provides features similar to the FP-SNS-ALLMEMS1 function pack, but with a different implementation for ultra-low power consumption.
The package also enables advanced functions such as voice communication over BLE, sound source localization and acoustic beam forming using inputs from multiple microphones, as well as sensor data fusion and accelerometer-based real-time activity recognition, audio data logging and MEMS sensor data logging on SD card.
This package, together with the suggested combination of STM32 and ST devices, can be used to develop specific wearable applications or smart things applications in general, where ultra-low power consumption is a key requirement.
The software runs on the STM32 microcontroller and includes all the necessary drivers to recognize the devices on the STM32 Nucleo development board and expansion boards, as well as on the STEVAL-BCNKT01V1 and STEVAL-STLKT01V1 evaluation boards.
- Complete firmware to develop an IoT node with BLE connectivity, digital microphone, environmental and motion sensors
- Middleware libraries for sensor data fusion and accelerometer-based real-time activity recognition, acoustic source localization and beam forming, audio processing and streaming over BLE communication profile, and SD card data logging
- Compatible with BlueMS application for Android/iOS, to perform sensor data reading, audio and motion algorithm feature demo, and firmware update over the air (FOTA)
- Implementation based on the use of an RTOS, targeting ultra-low power consumption use cases with battery operated devices
- Sample implementation available for STEVAL-BCNKT01V1 and STEVAL-STLKT01V1 evaluation boards and for X-NUCLEO-CCA02M1, X-NUCLEO-IKS01A2 and X-NUCLEO-IDB05A1 connected to a NUCLEO-F446RE or NUCLEO-L476RG board
