Android串口通信工具

SerialPortUtil

Android串口通信简单封装，可以用于和连接串口的硬件通信或者进行硬件调试

集成方法：

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

//Add the dependency
dependencies {
	       implementation 'com.github.tyhjh:SerialPortUtil:1.0.0' 
	}

调用方法

读取文件权限应该是需要的

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

获取所有串口地址

String[] devicesPath = new SerialPortFinder().getDevicesPaths();

打开串口，设置读取返回数据超时时间

SerialPortService serialPortService = new SerialPortBuilder()
                        .setTimeOut(100L)
                        .setBaudrate(9600)
                        .setDevicePath("dev/ttyS4")
                        .createService();

发送指令

//发送byte数组数据
byte[] receiveData = serialPortService.sendData(new byte[2]);

//发送16进制的字符串
byte[] receiveData = serialPortService.sendData("55AA0101010002");
Log.e("MainActivity：", ByteStringUtil.byteArrayToHexStr(receiveData));

打开或者关闭日志,默认关闭

serialPortService.isOutputLog(true);

//关闭串口

serialPortService.close();
