HM-10 블루투스통신을 공부하고있는데 1:1통신은 가능한데 멀티페어링이 안되더라고요

BLUETOOTH4.0부터 멀티페어링이 가능한걸로 아는데 코드를 바꿔야 멀티페어링이 가능한가요?

#include  

SoftwareSerial mySerial(2, 3); // RX, TX

void setup()  

{

  // Open serial communications and wait for port to open:

  Serial.begin(9600);

  Serial.println("Goodnight moon!");

  // set the data rate for the SoftwareSerial port

  mySerial.begin(9600);

}

void loop() // run over and over

{

  // Receive from bluetooth and send it to PC

  if (mySerial.available())

    Serial.write(mySerial.read());

  // Receive from PC and send it to bluetooth

  if (Serial.available())

    mySerial.write(Serial.read());

}
