Android serial port read/write library.

## Quick Start

1. Import AAR

    Gradle or Download [SerialPort](https://github.com/lalakii/android_easy_serial_port/releases)

    ```kotlin

   //kotlin

    dependencies {

        implementation("cn.lalaki:SerialPort.Android:1.4")

    }

    ```

    ```groovy

   //groovy

    dependencies {

        implementation 'cn.lalaki:SerialPort.Android:1.4'

    }

    ```

2. Code Sample

   ```kotlin

   //Kotlin

   val b115200 = "0010002".toInt(8)

   val serialPort = SerialPort("/dev/ttySX", b115200, object : SerialPort.DataCallback {

       override fun onData(data: ByteArray) {

           //...

       }

   })

   

   serialPort.write(byte[])

   

   serialPort.close()

   ```

    

   ```java 

   //Java

   import cn.lalaki.SerialPort;

   

   SerialPort serialPort1 = new SerialPort("/dev/ttySX",0010002,null);  // write only

   serialPort1.write(byte[]);

   

   SerialPort serialPort2 = new SerialPort("/dev/ttySX", 0010002, new SerialPort.DataCallback() {

       @Override

       public void onData(@Nullable byte[] data) {

           //...

       }

   });

   serialPort2.write(byte[]);

   serialPort2.close();

   ```

3. Params

    ```java

    new SerialPort(path, speed, callback);

    ```

   

   | param           | value  |   type    | example |

   |:----------------| ----  |:---------:| ---- |

   | path            | Serial port path |  String   | "dev/ttyS0" |

   | speed is baud rate | See [termbits.h](https://github.com/torvalds/linux/blob/master/include/uapi/asm-generic/termbits.h) |  int  | B9600 value is 0000015, B115200 value is 0010002 |

   | callback        | DataCallback | interface | ... |

4. Common problems

    ```bash

    ### Checking Permissions

    adb shell

    su

    setenforce 0

    chmod 0766 /dev/ttyS*

    ```
