 ### IMU
 
 The Nicla Voice features an advanced IMU and a magnetometer, which allows the board to sense motion, orientation, and magnetic fields. The IMU on the Nicla Voice board is the BMI270 from Bosch®. It consists of a 3-axis accelerometer and a 3-axis gyroscope. They can provide information about the board's motion, orientation, and rotation in a 3D space. The BMI270 is designed for wearables and offers low power consumption and high performance, making it suitable for various applications, such as gesture recognition, motion tracking, or stabilization.

 - `NDP.h` for the Nicla Voice board's basic functions and the magnetometer control.
 - Macros are defined for checking the status of the magnetometer; these macros allow the sketch to detect and handle sensor errors. 
 
-Next, user functions `ledBlueOn()`, `ledGreenOn()`, and `ledRedBlink()` definition: 
+Next, user function `ledRedBlink()` definition: 
 
-- These functions allow the onboard LEDs to flash specific colors to indicate different states: blue for a successful match, green for an event, and red to indicate an error.

 Next, in the `setup()` function:
 
 - The serial communication is initialized at a baud rate of 115200.
 - The Nicla Voice board is initialized, and the LDO regulator (used for putting the board into power-saving mode) is disabled to avoid communication problems with the magnetometer. 
 - Error and event handlers are initialized.
-- NDP processor is initialized; this process includes populating the external Flash memory of the board with the NDP processor's internal microcontroller firmware (`mcu_fw_120_v91.synpkg`), the NDP processor's internal DSP firmware (`dsp_firmware_v91.synpkg`), and the Machine Learning model (`ei_model.synpkg`).
