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
