Debug is working but release not - Kotlin receives data via Bluetooth

Question

I am working on Bluetooth receiving and sending data. I can send data via Bluetooth but it doesn't work the receive data. I want to get string data and split it. And the split data will show the list view. Since data import is not working, I created string data and called the split method, but it didn't work here either in a release. Can you help me? Here are my Activity codes;

        var mUUID: UUID = UUID.fromString("00001101-0000-1000-8000-00805F9B34FB")
        var mBluetoothSocket: BluetoothSocket? = null
        lateinit var mProgress: ProgressDialog
        lateinit var mBluetoothAdapter: BluetoothAdapter
        var mIsConnected: Boolean = false
        lateinit var mAddress: String
        lateinit var inputStream: InputStream
    }
    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        binding = ActivityListBinding.inflate(layoutInflater)
        val view = binding.root
        setContentView(view)
        mAddress = intent.getStringExtra(MainActivity.EXTRA_ADDRESS).toString()
        ConnectToDevice(this).execute()
        run()
        binding.deneme.setOnClickListener {
            sendCommand("denemebeyza")
            Log.d("mesajBT", "onCreate: mesaj gonderildi")
        }
        val string2: String = "deneme, deneme02K, deneme90,klm08B,bitti."
        splitList(string2)

    }


    private fun sendCommand(input: String) {
        if (mBluetoothSocket != null) {
            try {
                mBluetoothSocket!!.outputStream.write(input.toByteArray())
            } catch (e: IOException) {
                e.printStackTrace()
            }
        }
    }

  
    fun run() {

        val LOGTAG: String ="ReadListString"
        Log.i(LOGTAG, Thread.currentThread().name)
        val buffer = ByteArray(8)
        var bytes: Int
        val text1: TextView = binding.text2
        var readText : String
        Log.d("mesajBt", "mesaj metodu")

        //Loop to listen for received bluetooth messages
        if (mBluetoothSocket != null) {
            while (true) {
                bytes = try {
                    bytes = inputStream.read(buffer) ?:0
                    readText = String(buffer, 0, bytes)
                    Log.e("Arduino Message", readText)
                } catch (e: IOException) {
                    e.printStackTrace()
                    Log.d("Else", "message alinamadi.")
                    break
                }
                text1.text =readText
            }
        }
    }
    fun splitList(output: String) {
        val listView : ListView= binding.list1
        val textView: TextView= binding.text1
        if (mBluetoothSocket != null) {
            try {
                val list: List<String> = output.split(",").toList()
                var arrayAdapter: ArrayAdapter<*>
                for (it in list) {
                    Log.e("TAG", "splitList: $list ")
                    val list2: ArrayList<String> = ArrayList(list)
                    textView.text = list2.toString()
                }
                arrayAdapter = ArrayAdapter(this, android.R.layout.simple_list_item_1, list)
                listView.adapter=arrayAdapter
            } catch (e: IOException) {

Since there will be commas between words in data coming from Bluetooth, I used a comma as a separator in the split method. After some research, I corrected a few mistakes. You can change the value of the bytes as 8-16-32-64 according to the incoming data type and size. Receive method is here

private fun run() {
        //Loop to listen for received bluetooth messages
        if (mBluetoothSocket != null) {

            val TAG: String = "ReadList-run"
            Log.i(TAG, Thread.currentThread().name)
            val buffer = ByteArray(1024)
            var bytes: Int
            var readText: String
            Log.e("mesajBt", "mesaj metodu")
            while (true) {
                try {
                    bytes = inputStream.read(buffer)
                    readText = String(buffer, 0, bytes)
                    Log.e("Arduino Message", readText)
                    splitlist(readText)
                    break
                } catch (e: IOException) {
                    e.printStackTrace()
                    Log.d("Else", "message alinamadi.")
                    break
                }
            }
        }
    }

Here is my split method

 fun splitList(output: String) {
        if (mBluetoothSocket != null) {
            try {
                val list: List<String> = output.split(",").toList()
                for (it in list) {
                    Log.e("TAG", "splitList: $list ")
                }
            } catch (e: IOException) {
                e.printStackTrace()
            }
            // [A, B, C, D]
        }
    }
