BlueToothUtils

Usage

dependency

This tool has only one file BlueToothUtils.java,copy it!

manifests

Add the following permissions

    <!-- 蓝牙权限 -->
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN" />
    <uses-permission android:name="android.permission.BLUETOOTH" />
    <!-- Android 5.0以上蓝牙好需要位置权限 -->
    <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
    <uses-permission android:name="andriod.permission.ACCESS_FINE_LOCATION" />

Initialize in your application

mBtu = new BlueToothUtils(this);

In your Bluetooth settings Activtiy

Get BlueToothUtils instance

btu=MyApplication.getmBtu();

Turn on Bluetooth

//打开蓝牙
btu.enableBluetooth(new BlueToothUtils.enableBluetoothListener() {
  @Override
   public void enableSuccess() {
     //打开蓝牙后才能进行后续操作(这需要一段时间)
      }
   });

Get paired devices

btu.queryingPairedDevices();

Get the scanned device

  //获取扫描到的设备
    btu.discoveringDevices(12000, new BlueToothUtils.discoveringDevicesListener() {
     @Override
     public void getDiscouveredDevice(BluetoothDevice bluetoothDevice) {
       Log.i("BTU","DiscoveringDevices:"+bluetoothDevice.getName()+":"+bluetoothDevice.getAddress());
       }
     });

Make current blue can be scanned by other devices

//使当前手机可以被其他设备扫描到,可见时间120秒
 btu.enablingDiscoverability(120);

Connect the specified Bluetooth device and reader port

 //连接指定的蓝牙设备和读写口(保存连接状态，在应用其他地方读写)
  btu.bleConnect(bluetoothDevice,"0000ffe1-0000-1000-8000-00805f9b34fb");

In your Bluetooth Reading or writing Activtiy

Get BlueToothUtils instance

 //获取蓝牙实例
        if (null == mBtu) {
            mBtu = MyApplication.getmBtu();
        }

add Bluetooth read and write success callback

 //蓝牙读写成功后回调
        mBtu.addInteractiveDataListener(new BlueToothUtils.interactiveDataListener() {
            @Override
            public void writeSuccess(String data) {

            }
            @Override
            public void readSuccess(byte[] data) {

            }

            @Override
            public void replyData(byte[] data) {
                //注意这在子线程
            }
        });

Determine if Bluetooth is connected

mBtu.blueIsConnected()//返回boolean

Write data (unlimited length)

 mBtu.blueStringWrite(String info,String encode);//传入对字符数组的编码格式

Write data (less than 20 bytes)

mBtu.bleBytesWrite(byte[] data)

read data

mBtu.bleBytesRead()

Turn off Bluetooth

mBtu.closeBlueTooth()

Turn off Bluetooth and log off the broadcast

mBtu.release()
