Connecting a SparkFun PPG to an Arduino

#include <Wire.h>

SparkFun_Bio_Sensor_Hub bioHub;

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

  Serial.println("Initializing sensor...");

  if (!bioHub.begin()) {
    Serial.println("Sensor not found! Check connections.");
    while (1); // Stalls here if sensor is not present.
  }

  delay(1000); // Wait for the sensor to stabilize

  bioHub.configBpm(3); // PPG mode: 3 = RED + IR LED

  Serial.println("Sensor ready, sending PPG data...");
}

void loop() {
  bioData data = bioHub.readBpm(); // Read data

  if (data.status == 0) { // If status is 0, data is valid
    Serial.print("IR: ");
    Serial.print(data.irLed);
    Serial.print("\tRED: ");
    Serial.print(data.redLed);
    Serial.print("\tHeart Rate: ");
    Serial.print(data.heartRate / 10.0); // heartRate LSB=0.1bpm
    Serial.print("\tConfidence: ");
    Serial.print(data.confidence);
    Serial.print("\tStatus: ");
    Serial.print(data.status);
    Serial.print("\tOxygen: ");
    Serial.println(data.oxygen);
  } else {
    Serial.print("Waiting for data, status: ");
    Serial.println(data.status);
  }

  delay(50); // Approximately 20 Hz sample rate
}

As output, I see these lines going down infinitely:
IR: 0 RED: 0 Heart Rate: 0.00 Confidence: 0 Status: 0 Oxygen: 0
How can I solve this?
