使用SerialTerminal mik3y / usb-serial-for-android KOTLIN

如何解决使用SerialTerminal mik3y / usb-serial-for-android KOTLIN

大家好，我试图在我的App android中做一个串行终端，但是我停止了:(，现在我可以在文本视图中追加内容了，但是它不是真实数据。

        val response = ByteArray(8192)       
        

        button2.setonClickListener {
        setContentView(R.layout.fragment_terminal_layout)

        val manager=getSystemService(USB_SERVICE) as UsbManager
        tvterminalRawData.append("$manager \n\n\n")
        val availableDrivers = UsbSerialProber.getDefaultProber().findAllDrivers(manager)
        tvterminalRawData.append("$availableDrivers \n\n\n")
        if (availableDrivers.isEmpty()){
            tvterminalRawData.text = "empy"
            return@setonClickListener
        }
        val driver =availableDrivers[0]
        println(driver)
        tvterminalRawData.append("$driver \n\n\n")
        val connection =manager.openDevice(driver.device) ?: return@setonClickListener
        val port = driver.ports.get(0)
        //tvterminalRawData.text = tvterminalRawData.text.toString() + port.toString()
        tvterminalRawData.append(port.toString() + "\n\n\n")
        port.open(connection)
        port.setParameters(9600,8,UsbSerialPort.STOPBITS_1,UsbSerialPort.PARITY_NONE)

        val readd=port.read(response,2000)

        //len=port.read(response,READ_WAIT_MILLIS).toString()
        tvterminalRawData.append(readd.toString())
        tvterminalRawData.append(readd.toString())
        tvterminalRawData.append(readd.toString())
        tvterminalRawData.append(readd.toString())
        tvterminalRawData.append(readd.toString())
        tvterminalRawData.append(readd.toString())


        //leno = port.write("7E 00 16 10 00 00 13 A2 00 41 7D F5 79 FF FE 00 00 47 00 13 A2 41 7D F5 82 E0",2000).toString()
        //tvterminalRawData.append(leno)






    }

在此部分中，您可以看到我手机的一些屏幕截图 enter image description here

如果您看到的话，在屏幕截图中我有6个“ 1”，因为我仅将该块用于调试，但是“ 1”不是我试图从Arduino的Serialprintln中读取的真实数据

        tvterminalRawData.append(readd.toString())
        tvterminalRawData.append(readd.toString())
        tvterminalRawData.append(readd.toString())
        tvterminalRawData.append(readd.toString())
        tvterminalRawData.append(readd.toString())
        tvterminalRawData.append(readd.toString())
