* @brief This is an example on how the Detector Distance API can be used
* @n
* This example executes as follows:
* - Retrieve HAL integration
* - Initialize distance detector resources:
* + Create distance detector configuration
* + Update configuration settings
* + Create Distance detector handle
* + Create buffer for detector calibration data
* + Create buffer for sensor data
* - Create and calibrate the sensor
* - Calibrate the detector
* - Measure distances with the detector (loop):
* + Prepare sensor with the detector
* + Measure and wait until a read can be done
* + Print IQ data amplitude
* + Process measurement and print the result
* + Handle "calibration_needed" indication
* - Cleanup:
* + Destroy detector configuration
* + Destroy detector handle
* + Destroy sensor data buffer
* + Destroy detector calibration data buffer
