Getting started with the STM32Cube function pack for IoT node with BLE connectivity, digital microphone, environmental and motion sensors

Introduction

FP-SNS-ALLMEMS1 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 STBLESensor app, to view real-time environmental sensor data, motion sensor data, digital microphone levels and battery level.

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, carry position, gesture recognition, motion intensity recognition, audio data logging and MEMS sensor data logging on SD card.

Moreover, it provides real-time information about the user current pose based on data from a device, working mode (sitting/ standing desk position), tilt angles of the device, the repetitions of various fitness activities performed and the vertical movement.

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.

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 , STEVAL-MKSBOX1V1 and

STEVAL-STLKT01V1 evaluation boards.

Architecture

The STM32Cube function packs leverage the modularity and interoperability of STM32 Nucleo and expansion boards with STM32Cube and expansion software to create functional examples representing some of the most common use cases in each sphere of application.

These software function packs are designed to fully exploit the underlying STM32 ODE hardware and software components to best satisfy the final user application requirements.

Function packs may also include additional libraries and frameworks not present in the original expansion software packages, thus enabling new functions and creating more pertinent and usable systems for developers.

To access and use the sensor expansion board, the application software uses:

• STM32Cube HAL layer : provides a simple, generic and multi-instance set of generic and extension APIs

(application programming interfaces) to interact with the upper layer application, libraries and stacks. It is directly based on a generic architecture and allows the layers that are built on it, such as the middleware layer, to implement their functions without requiring the specific hardware configuration for a given microcontroller unit (MCU). This structure improves library code reusability and guarantees easy portability across other devices.

• Board support package (BSP) layer : supports the peripherals on the STM32 Nucleo board (except the

MCU) with a limited set of APIs providing a programming interface for certain board-specific peripherals like the LED, the user button, etc., and helps determine the specific board version. For the sensor expansion board, it provides the programming interface for various inertial and environmental sensors and support for initializing and reading sensor data.

STEVAL-MKSBOX1V1 evaluation board

This software is based on the STM32CubeHAL. It extends STM32Cube by providing a board support package

(BSP) for the BlueNRG-MS and BlueNRG-2 , sensor expansion board and middleware components for communication with other Bluetooth low energy devices, for sensor data fusion, real-time audio library, voice communication over Bluetooth low energy and SD card data logging.

The package contains audio libraries (AcousticBF, AcousticSL and BlueVoiceADPCM) and and motion sensor libraries (MotionAR, MotionCP, MotionFA, FusionFX, MotionGR, MotionID, MotionPE, MotionSD, MotionTL,

MotionVC) useful for sensing applications based on BLE communication.

FP-SNS-ALLMEMS1 also contains FatFs generic FAT file system module which provides access to storage devices such as memory card and hard disk (feature available only for the STEVAL-STLCS01V1 and STEVAL-

MKSBOX1V1 evaluation boards).

The motion algorithms are managed through special software designed for mobile and wearable applications and are strictly limited to work with accelerometer and pressure data only, to facilitate low power consumption strategies commonly required in these applications, in compliance with Bluetooth specifications.

The provided drivers abstract low-level hardware details, so middleware components and applications can access the sensors in a hardware-independent manner.

The package includes a sample application to transmit the values read from all the sensors to a Bluetooth low energy-enabled device such as an Android™ or iOS™.

The STBLESensor Android/iOS application, available on the respective application stores, displays the values read from sensors. The application also allows firmware update over the air as well as displaying battery information.

The STEVAL-STLKT01V1 and STEVAL-MKSBOX1V1 boards go in shutdown mode if they are not connected to an Android/iOS device for a period longer than a fixed range time.

F446RE / NUCLEO-F401RE / NUCLEO-L476RG , STEVAL-BCNKT01V1 and STEVAL-STLKT01V1 platforms through the IAR Embedded Workbench for ARM, RealView Microcontroller Development Kit ( MDK-ARM ) and Integrated Development Environment for STM32 ( STM32CubeIDE ).

Utilities : contains the boot loader binary ready to be flashed for the STM32F446RE , STM32F401RE ,

STM32L4R9ZI and STM32L476RG Nucleo boards.

Flash management

Apart from storing code, FP-SNS-ALLMEMS1 uses the flash memory for Firmware-Over-The-Air updates. It is divided into the following regions (see figure below):

the first region contains a custom boot loader

the second region contains the FP-SNS-ALLMEMS1 firmware

The third region is used for storing the FOTA before the update

Even if the STM32F446RE / STM32F401RE (512 KB), the STM32L476RG (1024 KB), STM32L4R9ZI (2048 KB) cache sizes and arrangements differ, we have used the same FLASH arrangement for both. The Meta Data

Manager is placed at the end of the flash (0x08007000 for STM32F446RE/STM32F401RE, 0x080FF000 for

STM32L476RG and 0x081FF000 for STM32L4R9ZI). For more information, refer to:

The boot process

1.5

The boot process

The FP-SNS-ALLMEMS1 cannot not be flashed at the beginning of the flash (address 0x08000000), and is therefore compiled to run from the beginning of the second flash region, at 0x08004000.

To enable this behavior, we set the vector table offset in Src/system_stm32f4xx.c (for STM32F401 and

STM32F446) and Src/system_stm32l4xx.c (for STM32L476 and STM32R9ZI) thus: #define

VECT_TAB_OFFSET 0x4000 .

UM2059 - Rev 10 page 7/87

UM2059 - Rev 10

UM2059

The boot process

We also changed the linker script. For example, the Linker script for FP-SNS-ALLMEMS1 running on

STM32F401RE and compiled using IAR Embedded Workbench for ARM is: define symbol __ICFEDIT_intvec_start__ = 0x08004000;

/*-Memory Regions-*/ define symbol __ICFEDIT_region_ROM_start__ = 0x08004000; define symbol __ICFEDIT_region_ROM_end__ = 0x0803FFFF; define symbol __ICFEDIT_region_RAM_start__ = 0x20000000; define symbol __ICFEDIT_region_RAM_end__ = 0x20017FFF;

/*-Sizes-*/ define symbol __ICFEDIT_size_cstack__ = 0x8000; define symbol __ICFEDIT_size_heap__ = 0x800;

Using the above linker script, the maximum usable code size is fixed at 240 KB.

You must flash the appropriate bootloader binary for STM32F446RE, STM32F401RE, STM32L476RG or

STM32L4R9ZI, found in the Utilities\BootLoader folder, to the first flash region (address 0x08000000).

Figure 4. BootLoader folder content

On any board reset:

• If there is a FOTA in the third Flash region, the boot loader overwrites the second Flash region (with FP-

SNS-ALLMEMS1 firmware) and replaces its content with the FOTA and restarts the board.

• If there is no FOTA, the boot loader jumps to the FP-SNS-ALLMEMS1 firmware.

Firmware-Over-The-Air (FOTA) update

To function, the script must be modified with:

• the installation path for OpenOCD

• the installation path for STM32 OpenOCD scritps

• and the Library path for OpenOCD

The OpenOCD script section to be edited is the following one.

# 1) Set the Installation path for OpenOCD

# example:

#OpenOCD_DIR="C:/ST/STM32CubeIDE_1.3.0/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.external

tools.openocd.win32_1.3.0.202002181050/tools"

OpenOCD_DIR=""

# 2) Set the installation path for stm32 OpenOCD scritps

# example:

#OpenOCD_CFC="C:/ST/STM32CubeIDE_1.3.0/STM32CubeIDE/plugins/com.st.stm32cube.ide.mcu.debug.op

enocd_1.3.0.202002181050/resources/openocd/st_scripts"

OpenOCD_CFC=""

# 3) Only for Linux/iOS add openocd library path to _LIBRARY_PATH:

# For iOS example:

#export DYLD_LIBRARY_PATH=${DYLD_LIBRARY_PATH}:${OpenOCD_DIR}"lib/"

# For Linux example:

#export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${OpenOCD_DIR}"lib/"

Firmware-Over-The-Air (FOTA) update

The FP-SNS-ALLMEMS1 firmware can be updated Over-The-Air (FOTA) through an Android/iOS device via

Bluetooth using the STBLESensor application (ver. 4.2.1 and above) available on their respective application market stores.

The application sends the update and associated CRC (cyclic-redundancy-check) value, which the FP-SNS-

ALLMEMS1 checks against the hardware cyclic redundancy check calculation unit on the STM32F446RE /

STM32F401RE / STM32L476RG / STM32L4R9ZI processor to ensure integrity. If the CRC calculation matches the

STBLESensor CRC value, the new firmware is written to the beginning of the third Flash region. A “magic number” setting signals the boot loader that a Firmware update has been received and checked, and is ready to replace the current FP-SNS-ALLMEMS1 firmware.

APIs

Detailed user-API technical information with full function and parameter descriptions is available in a compiled

HTML file in the package “Documentation” folder.

With the NUCLEO-F446RE , NUCLEO-F401RE and NUCLEO-L476RG boards, you can set up a terminal window

for the appropriate UART communication port (as per Figure 10. Terminal setting ) to control the initialization

phase.

UM2059 - Rev 10 page 14/87

UM2059

Sample application description

Note:

When connecting the micro-USB port to a PC, with STEVAL-MKSBOX1V1 and STEVAL-STLKT01V1 evaluation boards, you can set up a terminal window for the appropriate UART communication port (as per

Figure 10. Terminal setting ) to control the initialization phase. However, as it is necessary to register the USB

device, this is only possible when the STEVAL-MKSBOX1V1 (or STEVAL-STLKT01V1 ) starts initializing. In fact, a

5-second (10-second) delay has been added to the initialization phase to allow the user to monitor its progress.

Due to Flash size constraints, for the STEVAL-STLKT01V1 this feature is available only when the SD card data logging is not enabled.

You must modify the ALLMEMS1_config.h file by enabling the //#define ALLMEMS1_ENABLE_PRINTF line to enable this feature for the STEVAL-STLKT01V1 or STEVAL-MKSBOX1V1 , as it is disabled by default.

The SD card data logging is enabled by default. You must modify the ALLMEMS1_config.h file by disabling the

#define ALLMEMS1_ENABLE_SD_MEMS_RECORDING line to disable this feature for the STEVAL-STLKT01V1 or STEVAL-MKSBOX1V1 .

Sample application description

Note:

As shown in the console output above, the application sends:

•

3 short precision quaternions every 30 ms temperature/humidity/pressure data every 500 ms

3D accelerometer, 3D gyroscope and 3D magnetometer data every 50 ms signal noise microphone levels every 50 ms

You can change the transmission frequency of the sensor data via the STBLESensor Android/iOS application.

This application reads the accelerometer, magnetometer and gyroscope values at 100 samples/second. The

MotionFX (iNEMOEngine PRO) library combines these sensor values to produce and transmit 100 quaternions/ second to the client connected via Bluetooth low energy to reflect real motion using a vendor-specific BLE service.

The above also applies to the STEVAL-STLKT01V1 , STEVAL-MKSBOX1V1 and STEVAL-BCNKT01V1 evaluation boards.

UM2059 - Rev 10 page 16/87

Sample application description

These definitions in ALLMEMS1_config.h control the number of quaternions sent by the application to the

Bluetooth client:

• QUAT_UPDATE_MUL_10MS : defines the transmission rate for each set of quaternions by multiple of 10 ms.

• SEND_N_QUATERNIONS : defines the number of quaternions sent to each Bluetooth package.

By default, the application sends 3 quaternions every 30 ms.

The same allmems1_config.h file also defines:

• ALLMEMS1_DEBUG_CONNECTION and ALLMEMS1_DEBUG_NOTIFY_TRAMISSION to enable some debugging information for BLE communication

The MotionFX (INEMOEngine PRO) library has an auto-calibrating procedure and the calibration status is transmitted via BLE to the client:

• on the NUCLEO-F446RE or NUCLEO-F401RE or NUCLEO-L476RG boards, you can press the user button to reset the library calibration status and force a new auto-calibration procedure.

• for the STEVAL-STLKT01V1 , STEVAL-MKSBOX1V1 and STEVAL-BCNKT01V1 evaluation boards, this procedure can be done only through the STBLESensor application.

•

The MotionAR library is able to recognize the following activities:

• stationary

• walking fast walking jogging biking driving

•

STLCS01V1 SensorTile component board description

STEVAL-STLCS01V1 (SensorTile) is a highly integrated reference design that can be plugged into form-factor prototypes to add sensing and connectivity capabilities to new designs through a smart hub solution. It can also easily support development of monitoring and tracking applications as standalone sensor node connected to iOS/

Android smartphone applications.

The SensorTile comes in a very small square shape 13.5 x 13.5 mm. All the electronic components are on the top side of the pcb, while the bottom side has a small connector through which it is possible to easily plug and unplug it from a motherboard. The connector pinout is also replicated on 18 pcb pads that render the SensorTile a solderable system on module as well.

The module comes with pre-loaded FP-SNS-ALLMEMS1 (former BLUEMICROSYSTEM2) software that initializes all the sensors and the Bluetooth low energy radio. The “ST BlueMS” app, available free of charge on Apple

Store™ and Google Play™, is the easiest and fastest way to start using the SensorTile board and to experience a real activity monitoring system.

The SensorTile firmware package STSW-STLKT01 , built on the STM32Cube software technology, includes all the low level drivers to manage the on-board devices and system-level interfaces. It has been designed in order to be easily extended and personalized as starting point for development and customization of new dedicated applications.

All the firmware packages are freely available on www.st.com.

The Bluetooth radio power output is set by default at 0 dBm. The FCC and IC certifications refer to this operating value. The power output can be changed up to 8 dBm by reprogramming the device firmware, but the change of this operating value will require an update of the FCC and IC certifications, with additional radio emission tests to be performed.
