1/ Step : Create A New Project  add the code in  AndroidManiFest

        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/Theme.MyApplication"
        tools:targetApi="31">
        <activity
            android:name=".MainActivity"
            android:exported="true">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>

            <receiver android:name=".receivers.MyBroadcastReceiver"
                android:exported="true"
                tools:ignore="MissingClass,WrongManifestParent">
                <intent-filter>
                    <action android:name="android.intent.action.AIRPLANE_MODE" />
                    <action android:name="android.bluetooth.adapter.action.STATE_CHANGED" />
                </intent-filter>
            </receiver>

        </activity>


    </application>

</manifest>

2/Step :  Create A New Class BroadcastReceiver 

package com.example.app.receivers

import android.bluetooth.BluetoothAdapter
import android.content.BroadcastReceiver
import android.content.Context
import android.content.Intent
import android.util.Log

class MyBroadcastReceiver : BroadcastReceiver() {
    override fun onReceive(context: Context, intent: Intent) {
        when (intent.action) {
            Intent.ACTION_AIRPLANE_MODE_CHANGED -> {
                val isAirplaneModeOn = intent.getBooleanExtra("state", false)
                Log.d("MyBroadcastReceiver", "Airplane Mode is ${if (isAirplaneModeOn) "ON" else "OFF"}")
            }

            BluetoothAdapter.ACTION_STATE_CHANGED -> {
                val bluetoothState = intent.getIntExtra(BluetoothAdapter.EXTRA_STATE, BluetoothAdapter.STATE_OFF)
                when (bluetoothState) {
                    BluetoothAdapter.STATE_OFF -> Log.d("MyBroadcastReceiver", "Bluetooth is OFF")
                    BluetoothAdapter.STATE_ON -> Log.d("MyBroadcastReceiver", "Bluetooth is ON")
                }
            }
        }
    }
}

3/Step :  Add the code in MainActivity

import android.bluetooth.BluetoothAdapter
import android.content.BroadcastReceiver
import android.content.Context
import android.content.Intent
import android.content.IntentFilter
import android.os.Bundle
import android.util.Log
import androidx.appcompat.app.AppCompatActivity

class MainActivity : AppCompatActivity() {
    private lateinit var myReceiver: BroadcastReceiver

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)

        // Create the BroadcastReceiver
        myReceiver = object : BroadcastReceiver() {
            override fun onReceive(context: Context, intent: Intent) {
                when (intent.action) {
                    Intent.ACTION_AIRPLANE_MODE_CHANGED -> {
                        val isAirplaneModeOn = intent.getBooleanExtra("state", false)
                        Log.d("MainActivity", "Airplane Mode is ${if (isAirplaneModeOn) "ON" else "OFF"}")
                    }

                    BluetoothAdapter.ACTION_STATE_CHANGED -> {
                        val bluetoothState = intent.getIntExtra(BluetoothAdapter.EXTRA_STATE, BluetoothAdapter.STATE_OFF)
                        when (bluetoothState) {
                            BluetoothAdapter.STATE_OFF -> Log.d("MainActivity", "Bluetooth is OFF")
                            BluetoothAdapter.STATE_ON -> Log.d("MainActivity", "Bluetooth is ON")
                        }
                    }
                }
            }
        }

        // Register the receiver
        val filter = IntentFilter().apply {
            addAction(Intent.ACTION_AIRPLANE_MODE_CHANGED)
            addAction(BluetoothAdapter.ACTION_STATE_CHANGED)
        }
        registerReceiver(myReceiver, filter)
    }

    override fun onDestroy() {
        super.onDestroy()
        // Unregister the receiver
        unregisterReceiver(myReceiver)
    }
}
