 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.
