2 Fingerprint sensor AS608 menggunakan 1 Arduino UNO

[adtyntang]

Halo, saya memiliki masalah dalam menggunakan 2 sensor fingerprint AS608 dalam 1 Arduino UNO. apabila hanya 1 sensor saja yang diaktifkan, sensor dapat terbaca pada serial monitor dan dapat digunakan. namun jika 2 sensor yang diaktifkan, sensor tidak terbaca (device not found) dan tidak dapat digunakan.
Dan saya memiliki masalah juga tentang reset sidik jari menggunakan button.
Adakah yang dapat membantu saya? Berikut program saya untuk 2 sensor fingerprint ini

#include <Adafruit_Fingerprint.h>
#include <SoftwareSerial.h>

SoftwareSerial mySerial(4, 5);
SoftwareSerial mySerial2(2, 3); // Define another SoftwareSerial instance for the second fingerprint module

Adafruit_Fingerprint finger = Adafruit_Fingerprint(&mySerial);
Adafruit_Fingerprint finger2 = Adafruit_Fingerprint(&mySerial2); // Create an instance for the second fingerprint module

const int buttonPin = 4; // Assign the button switch to pin 4

void setup()
{
  Serial.begin(9600);
  while (!Serial);
  delay(100);
  pinMode(9, OUTPUT);
  pinMode(10, OUTPUT);
  pinMode(buttonPin, INPUT_PULLUP);
  Serial.println("Program Dasar Akses Sidik Jari Arduino");

  finger.begin(57600);
  finger2.begin(57600); // Initialize the second fingerprint module

  if (finger.verifyPassword() && finger2.verifyPassword())
  {
    Serial.println("Found fingerprint sensors!");
  }
  else
  {
    Serial.println("Did not find fingerprint sensors :(");
    while (1) { delay(1); }
  }
  Serial.println("Waiting for valid finger...");
}

void loop()
{
 if (digitalRead(buttonPin) == LOW)
  {
    addFingerprint();
    delay(1000); // Debounce delay to avoid multiple reads
  }
  else
  {
    getFingerprintID();
  }
}

uint8_t getFingerprintID()
{
  uint8_t p = finger.getImage();
  switch (p)
  {
    case FINGERPRINT_OK:
      Serial.println("Image taken");
      break;

      return p;
    default:

      return p;
  }

  // OK converted!
  p = finger.fingerFastSearch();
  if (p == FINGERPRINT_OK)
  {

  digitalWrite(13, HIGH);
  delay(3000);
  digitalWrite(13, LOW);

  return finger.fingerID;
}

void addFingerprint()
{
  Serial.println("Put your finger on the sensor to add a new fingerprint...");
  while (!finger.getImage())
  {
    // Wait until a finger is placed on the sensor
  }

  int fingerprintID = -1;

        }
        else

    }
    else

    }

  }
}

Tolong bantu saya, Terimakasih
