Failed to boot VL53L0X

Using Arduino Programming Questions

Hi...
I have a project using VL53L0X sensor, i have library from Arduino Code | Adafruit VL53L0X Time of Flight Micro-LIDAR Distance Sensor Breakout | Adafruit Learning System, then found "Failed to boot VL53L0X" written on serial monitor

I connect

VL53L0X ---------- Arduino
VCC _______ 5V
GND _______ GND
SCL _______ A5
SDA _______ A4

This is the code :

#include "Adafruit_VL53L0X.h"

Adafruit_VL53L0X lox = Adafruit_VL53L0X();

void setup() {
Serial.begin(115200);

// wait until serial port opens for native USB devices
while (! Serial) {
delay(1);
}

Serial.println("Adafruit VL53L0X test");
if (!lox.begin()) {
Serial.println(F("Failed to boot VL53L0X"));
while(1);
}
// power
Serial.println(F("VL53L0X API Simple Ranging example\n\n"));
}

void loop() {
VL53L0X_RangingMeasurementData_t measure;

Serial.print("Reading a measurement... ");
lox.rangingTest(&measure, false); // pass in 'true' to get debug data printout!

if (measure.RangeStatus != 4) { // phase failures have incorrect data
Serial.print("Distance (mm): "); Serial.println(measure.RangeMilliMeter);
} else {
Serial.println(" out of range ");
}

delay(100);
}

Then, it was written below the code while uploading

Sketch uses 17428 bytes (6%) of program storage space. Maximum is 253952 bytes.
Global variables use 1236 bytes (15%) of dynamic memory, leaving 6956 bytes for local variables. Maximum is 8192 bytes.

Please help me to solve it, thank you...

Those are all warnings, not errors. You should search for the "I2C scanner sketch" and download it and run it to make sure it can detect your device on the i2c bus. If it does not, then the wiring is wrong. If it does, then check to make sure it is at the address the software expects.
