android-serialport-api

Step 1. Add the JitPack repository to your build file

Add it in your root build.gradle at the end of repositories:

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

Step 2. Add the dependency

dependencies {
        compile 'com.github.kongqw:AndroidSerialPort:1.0.1'
}

查看串口

SerialPortFinder serialPortFinder = new SerialPortFinder();
ArrayList<Device> devices = serialPortFinder.getDevices();

打开串口

初始化

mSerialPortManager = new SerialPortManager();

添加打开串口监听

mSerialPortManager.setOnOpenSerialPortListener(new OnOpenSerialPortListener() {
    @Override
    public void onSuccess(File device) {
        
    }

    @Override
    public void onFail(File device, Status status) {

    }
});

添加数据通信监听

mSerialPortManager.setOnSerialPortDataListener(new OnSerialPortDataListener() {
    @Override
    public void onDataReceived(byte[] bytes) {
        
    }

    @Override
    public void onDataSent(byte[] bytes) {

    }
});

打开串口

• 参数1：串口
• 参数2：波特率
• 返回：串口打开是否成功

boolean openSerialPort = mSerialPortManager.openSerialPort(device.getFile(), 115200);

发送数据

• 参数：发送数据 byte[]
• 返回：发送是否成功

boolean sendBytes = mSerialPortManager.sendBytes(sendContentBytes);

关闭串口

mSerialPortManager.closeSerialPort();

PS：传输协议需自行封装
