#include <SoftwareSerial.h>

SoftwareSerial mySerial(3,4); // RX, TX PIN

String str;

void setup() {
  Serial.begin(9600);
  Serial.println("Enter AT Commands:");
  mySerial.begin(9600);
}

void loop() {
  if(mySerial.available()){
    Serial.write(mySerial.read());
  }
  if(Serial.available()){
    mySerial.write(Serial.read());
  }
}

Sterowanie Arduino przez Bluetooth za pomocą aplikacji Arduino bluetooth controller

#include <SoftwareSerial.h>

SoftwareSerial mySerial(3, 4);  // RX, TX PIN

char data = 0;  //Variable for storing received data
void setup() {
  mySerial.begin(9600);  //Sets the baud for serial data transmission
  pinMode(13, OUTPUT);   //Sets digital pin  13 as output pin
}
void loop() {
  if (mySerial.available() > 0)  //  Send data only when you receive data:
  {
    data = mySerial.read();  //Read  the incoming data & store into data
    if (data == '1')           // Checks whether value of data is equal to 1
      digitalWrite(13, HIGH);  //If value is 1 then LED turns ON
    else if (data == '0')      //  Checks whether value of data is equal to 0
      digitalWrite(13, LOW);   //If value is 0 then LED turns OFF
  }
