i am asking about the bluetooth pairing

#include "BluetoothSerial.h"
#include <BLEDevice.h>
#include <BLEServer.h>

BluetoothSerial ESP_BT;  // Classic Bluetooth object

void setup() {
  Serial.begin(115200);

  // Classic Bluetooth setup
  ESP_BT.begin("ESP32_BT_Device");  // Name the device
  Serial.println("Classic Bluetooth Device is Ready to Pair");

  // BLE setup
  BLEDevice::init("ESP32_BLE_Server");  // Name the BLE server
  BLEServer *pServer = BLEDevice::createServer();
  Serial.println("BLE Server is Running");
}

void loop() {
  // Handle Classic Bluetooth data
  if (ESP_BT.available()) {
    char received = ESP_BT.read();
    Serial.write(received);  // Echo received data
  }

  // BLE logic can be added here as needed for advanced configurations
}

#include "BluetoothSerial.h"
#include <BLEDevice.h>
#include <BLEServer.h>

BluetoothSerial ESP_BT;  // Classic Bluetooth object

void setup() {
  Serial.begin(115200);

  // Classic Bluetooth setup
  ESP_BT.begin("ESP32_BT_Device");  // Name the device
  Serial.println("Classic Bluetooth Device is Ready to Pair");

  // BLE setup
  BLEDevice::init("ESP32_BLE_Server");  // Name the BLE server
  BLEServer *pServer = BLEDevice::createServer();
  Serial.println("BLE Server is Running");
}

void loop() {
  // Handle Classic Bluetooth data
  if (ESP_BT.available()) {
    char received = ESP_BT.read();
    Serial.write(received);  // Echo received data
  }

  // BLE logic can be added here as needed for advanced configurations
