对 Ble 的封装，入口为 BleManager。  
提供 Sample，可以连接周围 Ble 设备，支持发送数据与接收数据

使用方法

AbsBleManager manager = BleManager.getInstance(context);
if(manager.isVisible()){
    manager.open(activity,new BleOpenListener() {
        @Override
        public void result(boolean open) {
            if (open) {
                manager.scan(new BluetoothAdapter.LeScanCallback() {
                         @Override
                         public void onLeScan(BluetoothDevice bluetoothDevice, int i, byte[] bytes) {
                            //获取附近蓝牙设备
                            if(yourDevice){
                                manager.connect(bluetoothDevice.getAddress());
                            }
                         }
                     }, new Runnable() {
                         @Override
                         public void run() {
                            //扫描结束
                         }
                     }, 5000);
            }
        })
}

//接收连接事件和数据
manager.registerBluetooth(this);

//发送数据
manager.sendData(new byte[],characterUUID，serviceUUID);

//断开连接
manager.disconnect();

需要动态获取权限
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>

静态权限
 <uses-permission android:name="android.permission.BLUETOOTH"/>
    <uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
