BluetoothLowEnergyLibrary

a library to ble

一、添加依赖

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.TitleZWC:BlueToothLowEnergyLibrary:v0.1-alpha'
}

二、声明并初始化BluetoothUtils。 private BluetoothUtils mBluetoothUtil;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
	setContentView(R.layout.activity_main);
	
	try {
        mBluetoothUtil = BluetoothUtils.getInstance(this);
    } catch (BluetoothNotSupportException e) {
        e.printStackTrace();
    }
}

三、设置蓝牙状态监听器。

    mBluetoothUtil.setOnBluetoothUtilStatusChangeLinsener(new BluetoothUtils.OnBluetoothUtilStatusChangeListener() {
        @Override
        public void onFindDevice(BluetoothDevice device) {
            Toast.makeText(MainActivity.this,"FindDevice",Toast.LENGTH_SHORT).show();
            mLeDeviceListAdapter.addDevice(device);
            mLeDeviceListAdapter.notifyDataSetChanged();
        }

        @Override
        public void onLeServiceInitFailed() {
            Toast.makeText(MainActivity.this, "LeServiceInitFailed", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onFindGattServices(List<BluetoothGattService> supportedGattServices) {
            Toast.makeText(MainActivity.this, "FindGattServices(", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onFindData(String uuid, String data) {
            Toast.makeText(MainActivity.this, "FindData", Toast.LENGTH_SHORT).show();
            dataValue.setText(data);
        }

        @Override
        public void onConnected() {
            Toast.makeText(MainActivity.this, "Connected", Toast.LENGTH_SHORT).show();
            mListView.setVisibility(View.GONE);
            gattView.setVisibility(View.VISIBLE);
        }

        @Override
        public void onDisconnected() {
            Toast.makeText(MainActivity.this, "Disconnected", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onFindGattService(BluetoothGattService supportedGattService) {
            Toast.makeText(MainActivity.this, "FindGattService", Toast.LENGTH_SHORT).show();
        }

        @Override
        public void onFindGattCharacteristic(BluetoothGattCharacteristic characteristic) {
            Toast.makeText(MainActivity.this, "FindGattCharacteristic", Toast.LENGTH_SHORT).show();
            
            mNotifyCharacteristic = characteristic;
            mBluetoothUtil.setCharacteristicNotification(
                    characteristic, true);
        }

        @Override
        public void onSendData(String UUID, String data) {
            dataValue.append("发送：" + data + "\r\n");
        }
    });

四、搜索蓝牙设备。

开始搜索：
    mBluetoothUtil.scanLeDevice(this, true);

停止搜索：
    mBluetoothUtil.scanLeDevice(this, false);

五、连接设备。

连接设备：
    mBluetoothUtil.connectDevice(MainActivity.this, device.getAddress(), sId, cId);

断开设备：
    mBluetoothUtil.disconnectionDevice();

六、传递数据。

发送数据
    mBluetoothUtil.sendData(mNotifyCharacteristic, edtSend.getText().toString());

接受数据
    在OnBluetoothUtilStatusChangeListener的onFindData(String uuid, String data)方法中处理

七、关闭资源。

mBluetoothUtil.onDestroy(this);
