Issue on VOC_and_eCO2_Gas_Sensor-SGP30

I have bought a SGP30 sensor to use with my Seeeduino mega, unfortunatly even after 12hours Im not able to store the base line using this code :

github.com

Seeed-Studio/SGP30_Gas_Sensor/blob/master/examples/baseline_operation_example/baseline_operation_example.ino

#include <Arduino.h>
#include <EEPROM.h>

#include "sensirion_common.h"
#include "sgp30.h"

#define LOOP_TIME_INTERVAL_MS  1000
#define BASELINE_IS_STORED_FLAG  (0X55)
//#define ARRAY_TO_U32(a)  (a[0]<<24|a[1]<<16|a[2]<<8|a[3])    //MSB first  //Not suitable for 8-bit platform

void array_to_u32(u32* value, u8* array) {
    (*value) = (*value) | (u32)array[0] << 24;
    (*value) = (*value) | (u32)array[1] << 16;
    (*value) = (*value) | (u32)array[2] << 8;
    (*value) = (*value) | (u32)array[3];
}
void u32_to_array(u32 value, u8* array) {
    if (!array) {
        return;
    }

It returns the following, can you help me ?
