Hi. I solved this problem in the end, In my situation, it turned out that the pox sensor stops frequently when I use bluetooth or Wi-Fi. So I just put some code that makes MAX30100 to restart periodically.

here is my code:

void loop() {

  if(index_minute%5==0){
    pox.begin();
  }
  if(power){
    UpdateSensors();
    SNB_task();
    send_data();
  }

Moreover, there were some issues with setup function. I don't know why, but the order between Bluetooth setup, pox setup, etc matters. Try changing their orders, or inserting short delays between codes. here is my code:

void SensorSetup() {
  
  // initialize both serial ports:
  //Serial.begin(115200);
  
  Wire.begin();
  
  // Temperature Sensor initializing
   //// spo2 Sensor initializing ///
  
  mpu.setup();
  
  delay(2000);
  
  SerialBT.begin(device_key);
  
  //Serial.print("Initializing PulseOximeter..");
  if (!pox.begin()) {
        //Serial.println("FAILED");
  } else {
        //Serial.println("SUCCESS");
  }
}
