(Android studios) не удалось получить данные arduino lightsensor

Здравствуйте, это я не в состоянии к извлечение данных от Arduino. Что-нибудь не так с моим кодом? Спасибо!


Код Android Studio

Код Arduino

<pre>#include <SoftwareSerial.h>

const int LightSensor = A1; //LightSensor pin at A1

int bluetoothTx = 2; //BTTX at pin 2
int bluetoothRx = 3; //BTRX at pin 3
int sensorValue = 0;

SoftwareSerial bluetooth(bluetoothTx, bluetoothRx);

void setup() {
  Serial.begin(9600);  // Begin the serial monitor at 9600bps
//
//  bluetooth.begin(115200);  // The Bluetooth Mate defaults to 115200bps
//  bluetooth.print("$");  // Print three times individually
//  bluetooth.print("$");
//  bluetooth.print("$");  // Enter command mode
//  delay(100);  // Short delay, wait for the Mate to send back CMD
//  bluetooth.println("U,9600,N");  // Temporarily Change the baudrate to 9600, no parity
//  // 115200 can be too fast at times for NewSoftSerial to relay the data reliably
  bluetooth.begin(9600);  // Start bluetooth serial at 9600
}

void loop() {
  sensorValue = analogRead(LightSensor);
  bluetooth.print(sensorValue);
  Serial.println(sensorValue);
  delay(2500);
}

Что я уже пробовал:

В основном все учебники онлайн.
