How to connect two phones to nano33 IoT via bluetooth

Hi,
I am trying to connect two phones with nano33 IoT via Bluetooth. I could connect one device via Bluetooth with the code below. However, I could not connect two devices at the same time. Would you teach me how to solve this issue ?

#include <ArduinoBLE.h>

void setup() {
  Serial.begin(9600);    // initialize serial communication
  while (!Serial);

  if (!BLE.begin()) {   // initialize BLE
    Serial.println("starting BLE failed!");
    while (1);
  }
  BLE.setLocalName("Nano33");  // Set name for connection
  BLE.advertise();  // Start advertising
  Serial.print("Peripheral device MAC: ");
  Serial.println(BLE.address());
  Serial.println("Waiting for connections...");
}

void loop() {
  BLEDevice central = BLE.central();  // Wait for a BLE central to connect
  if(central){
    // if a central is connected to the peripheral:
    Serial.print("MAC: ");
      // print the central's BT address:
    Serial.println(central.address());
    delay(1000);
  }
}

Thank you
