The last service is for transmitting/resetting the calibration status and enabling the following LSM6DS3 DIL24 expansion hardware features when it is mounted:  Pedometer
BLUEMICROSYSTEM2 software description STEVAL-STLKT01V1 6/37 DocID029208 Rev 2  Free Fall detection  Single tap detection  Double tap detection  Wake up detection  Tilt detection  3D orientation This software gathers the temperature, humidity, pressure, audio and motion sensors drivers for the HTS221, LPS25H, MP34DT01-M, LSM6DS0 (or LSM6DS3) and LIS3MDL devices, running on STM32. This package is compatible with the BlueMS Android/iOS (Version 2.0.0 or higher) application available at respective Play/iTunes stores, which can be used for displaying information sent via the Bluetooth low energy protocol. To use the hardware features of the LSM6DS3 DIL24 device, use BlueMS Android/iOS application version 2.2.0 or higher. 1.2 Architecture The software is based on the STM32CubeHAL hardware abstraction layer for the STM32 microcontroller. The package provides a Board Support Package (BSP) for the sensors expansion board and middleware components for serial communication with a PC. 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.

Ready to build projects are available for multiple IDEs. Application behavior can be controlled via UART with a terminal application and the following settings for the appropriate port. Figure 3: Terminal setting When you first press the reset button, the application:  starts initializing the UART, I²C and SPI interfaces  creates a random BLE MAC address and a random connection PIN necessary for making the connection  initializes the BLE hardware service adding the temperature, humidity, pressure, 3D gyroscope, 3D magnetometer, 3D accelerometer and microphone characteristics
STDK-STILECS01V1BLUEMICROSYSTEM2 software description DocID029208 Rev 2 9/37  initializes the BLE SW service adding the osx.MotionFX, osx.MotionAR, osx.MotionCP, osx.MotionGR and osx.AcousticSL libraries.  initializes the BLE console service adding the stdin/stdout and stderr characteristics  initializes the BLE config service transmitting/resetting the calibration status and enabling the LSM6DS3 DIL24 hardware features (if present).  checks whether the LSM6DS3 DIL24 extension is present.  Checks whether all the sensors are present and working.  controls whether the osxMotionFX, osxMotionAR, osxMotionCP, osxMotionGR and osxAcousticSL libraries have been initialized properly with valid licenses.  determines which BlueNRG expansion board is connected to the STM32 Nucleo board (X-NUCLEO-IDB04A1 or X-NUCLEO-IDB05A1) and hardware and firmware version information. If the LSM6DS3 DIL24 extension is present, the system is able also to understand a free fall situation because the DS3 generates one interrupts when there is free fall situation. This situations is transmitted over Bluetooth to the attached Android™/iOS™ device. Figure 4: Initialization phase As shown in the console output above, the application sends:  3 short precision quaternions every 30ms  Temperature/Humidity/Pressure data every 500ms  3D Accelerometer, 3D Gyroscope and 3D Magnetometer data every 50ms  signal noise microphone levels every 50ms This application reads the accelerometer, magnetometer and gyroscope values at 100 samples/second. The osxMotionFX (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.
BLUEMICROSYSTEM2 software description STEVAL-STLKT01V1 10/37 DocID029208 Rev 2 These definitions in osx_bms_config.h control how many quaternions the application sends 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 how many quaternions are sent on each Bluetooth package. By default, the application sends 3 quaternions every 30 ms. The same osx_bms_config.h file also defines:  ENV_UPDATE_MUL_10MS the transmission rate for Temperature/Pressure and Humidity/Lux  ACC_GYRO_MAG_UPDATE_MUL_10MS the transmission rate for Acc/Gyro and Magneto values  OSX_BMS_DEBUG_CONNECTION and OSX_BMS_DEBUG_NOTIFY_TRAMISSION to enable some debugging information for BLE communication  OSX_BMS_MOTIONAR to enable the osxMotionAR activity recognition algorithm  OSX_BMS_MOTIONCP to enable the osxMotionCP carry position recognition algorithm  OSX_BMS_MOTIONGR to enable the osxMotionGR gesture recognition algorithm  OSX_BMS_ACOUSTIC_MIC_ANGLE to enable the osxAcousticSL audio source localization algorithm (only NUCLEO-F401R Nucleo board) The osxMotionFX (INEMOEngine PRO) library has an autocalibrating procedure and the calibration status is transmitted via BLE to the client. By pressing the user button on the NUCLEO-F401RE (or NUCLEO-L476RG) board, it is possible to reset the library calibration status, thereby forcing a new autocalibration procedure. The osxMotionAR (INEMOEngine PRO) library is able to recognize the following activities:  Stationary  Walking  fast walking  jogging  biking  driving The osxMotionAR can be enabled via the OSX_BMS_MOTIONAR define in osx_bms_config.h. The osxMotionCP (INEMOEngine PRO) library recognizes and provides real-time information about how the user is carrying the board, which equates to the phone carry position:  on desk  in hand  near head  shirt pocket  trouser pocket  arm swing The osxMotionCP can be enabled via the OSX_BMS_MOTIONCP define in osx_bms_config.h. The osxMotionGR (INEMOEngine PRO) library is able to recognize gestures like:  pick up  glance  wake up in hand
STEVAL-STLKT01V1BLUEMICROSYSTEM2 software description DocID029208 Rev 2 11/37 The osxMotionGR can be enabled via the OSX_BMS_MOTIONGR define in osx_bms_config.h. The osxAcousticSL library is able to localize the audio sound source using the data acquired from the microphones. It can be enabled via the OSX_BMS_ACOUSTIC_MIC_ANGLE define in osx_bms_config.h. When an Android/iOS device is connected to the board, it is possible to control what the board transmit (see the following figure).
