Changing I^2C address when using 2 VL53L1X breakout boards

Qwiic System
1

This is my first time using an I2C system, so sorry if this is a dumb question, but… I am attempting to connect a set of 2 daisy-chained VL53L1X distance sensor breakout boards to an Arduino Uno. They are connected via a Qwiic shield and everything works fine with one, and when I plug 2 in I get readings from both just jumbled up. to differentiate between the two sensors, I attempted to change the address of one to 0x44 (default is 0x52) using this code.

#include <Wire.h>
#include "SparkFun_VL53L1X.h" //Click here to get the library: http://librarymanager/All#SparkFun_VL53L1X

//Optional interrupt and shutdown pins.
#define SHUTDOWN_PIN 2
#define INTERRUPT_PIN 3

SFEVL53L1X distanceSensor1;
SFEVL53L1X distanceSensor2;


uint8_t address2 = 0x44;

//Uncomment the following line to use the optional shutdown and interrupt pins.
//SFEVL53L1X distanceSensor(Wire, SHUTDOWN_PIN, INTERRUPT_PIN);

void setup(void)
{

  Serial.begin(115200);
  Serial.println("VL53L1X Qwiic Test");

  distanceSensor2.setI2CAddress(0x44);

  if (distanceSensor2.begin(0x44) != 0) //Begin returns 0 on a good init
  {
    Serial.println("Sensor2 failed to begin. Please check wiring. Freezing...");
    while (1)
      ;
  }

  if (distanceSensor1.begin() != 0) //Begin returns 0 on a good init
  {
    Serial.println("Sensor1 failed to begin. Please check wiring. Freezing...");
    while (1)
      ;
  }
  Serial.println("Sensor online!");
}

When I did that I got the following error

Can someone help me understand what I’m doing wrong here? I think that it is just a syntax error, but how are you supposed to set the address in the .begin command?

.begin() doesn’t take an address (or any) parameter, so remove that. I see you already have it set in distanceSensor2.setI2CAddress(0x44). Does that work once you remove it from the .begin()?
