#include <SoftwareSerial.h>
SoftwareSerial BTSerial(0, 1); //RX|TX

void setup(){
  Serial.begin(9600);
  BTSerial.begin(9600); // default baud rate
  Serial.println("AT commands: ");
}

void loop(){
  //Read from the HM-10 and print in Serial Moniter
  if(BTSerial.available()) {
      Serial.write(BTSerial.read());
  }

  //Read from the Serial Moniter and print to the HM-10
  if(Serial.available()) {
      BTSerial.write(Serial.read());
  }
}
