我正在尝试构建一个Android应用程序来使用Kotlin连接到HC-05蓝牙设备，但我无法连接它

<uses-permission android:name="android.permission.BLUETOOTH" />
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />

val bluetoothAdapter: BluetoothAdapter? = BluetoothAdapter.getDefaultAdapter()
if (bluetoothAdapter == null) {
    // 设备不支持蓝牙
} else {
    // 设备支持蓝牙
}

if (!bluetoothAdapter?.isEnabled) {
    val enableBluetoothIntent = Intent(BluetoothAdapter.ACTION_REQUEST_ENABLE)
    startActivityForResult(enableBluetoothIntent, REQUEST_ENABLE_BLUETOOTH)
}

val bluetoothDevice: BluetoothDevice? = bluetoothAdapter?.getRemoteDevice("HC-05的蓝牙地址")
val bluetoothSocket: BluetoothSocket? = bluetoothDevice?.createRfcommSocketToServiceRecord(MY_UUID)
bluetoothSocket?.connect()

val inputStream: InputStream? = bluetoothSocket?.inputStream
val outputStream: OutputStream? = bluetoothSocket?.outputStream

// 发送数据
val data = "Hello, HC-05"
outputStream?.write(data.toByteArray())

// 接收数据
val buffer = ByteArray(1024)
val bytesRead = inputStream?.read(buffer)
val receivedData = String(buffer, 0, bytesRead!!)
