Android serial port communication

Serial port library

Serial port communication library for Android

Setup

Add the library as aar dependency to your build.

Gradle

repositories {
    ...
    maven {url 'https://jitpack.io'}
}

implementation 'com.lexiang.library:serialcomm:1.0.2'

Usage

Open serial port and start reader, writer queue

//Set up serial port
SerialPortParams serialPortParams = new SerialPortParams.Builder()
       .serialPortBaudRate(Constants.SERIAL_BAUD_RATE_4800)
       .serialPortDataBits(Constants.DATABITS_8)
       .serialPortParity(Constants.PARITY_NONE)
       .serialPortStopBits(Constants.STOPBITS_1)
       .serialPortReaderIntervalTimeInMillis(10)  //set the read interval time
       .inputStreamSizeInByte(128)  //set the read buffer size
       .serialPortPath("/dev/ttyO3").build(); //set the device port path

//Create a dataHandler for read data from serial port
DataHandler readerHandler = new DataHandler() {
    @Override
    public void handleData(SerialPortData serialPortData) throws TRMError {
        if (serialPortData.getDataBytes() != null) {
            Log.i("IncomeDataHandler2", ByteUtil.toDisplayString(serialPortData.getDataBytes()));
        }
    }
};

//Create a dataHandler for write data into serial port
DataHandler writerHandler = new DataHandler() {
    @Override
    public void handleData(SerialPortData serialPortData) throws TRMError {

        if (SerialPortClient.getInstance().writeData(serialPortData.getDataBytes()) > -1) {
            if (serialPortData.getDataHandleListener() != null) {
                serialPortData.getDataHandleListener().onSucceed(ByteUtil.toDisplayString(serialPortData.getDataBytes()));
            }
        } else {
            if (serialPortData.getDataHandleListener() != null) {
                serialPortData.getDataHandleListener().onFailed(ByteUtil.toDisplayString(serialPortData.getDataBytes()));
            }
        }
    }
};

//init SerialPortReader
SerialPortReader.init(readerHandler);
//init SerialPortWriter
SerialPortWriter.init(writerHandler);
//open serial port
SerialPortClient.getInstance().start(serialPortStrategy,new ByteSerialPortReaderListener());

//Custom the SerialPortListener
SerialPortReaderListener serialPortReaderListener = new SerialPortReaderListener() {
    @Override
    public void onDataChanged(byte[] data) {
        //do sth whatever you'll do,such as byte decode digester
    }
};
SerialPortClient.getInstance().start(serialPortStrategy,serialPortReaderListener);
