Android蓝牙4.0开发_蓝牙开发实例源码下载

分享一个集成目前主流蓝牙的demo、android蓝牙4.0开发、项目中使用到了搜索BLE终端和读写BLE终端、另外还有在程序里面开房蓝牙、在Demo里面还处理了收到BLE终端数据交互的事件、代码里都有中文注释、要读性应该非常好的、应该会对开发有一定帮助、有兴趣的哥们可以下载看看

onCreate代码

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    getActionBar().setTitle(R.string.title_devices);
    mHandler = new Handler();

    // Use this check to determine whether BLE is supported on the device.  Then you can
    // selectively disable BLE-related features.
    if (!getPackageManager().hasSystemFeature(PackageManager.FEATURE_BLUETOOTH_LE)) {
        Toast.makeText(this, R.string.ble_not_supported, Toast.LENGTH_SHORT).show();
        finish();
    }

    // Initializes a Bluetooth adapter.  For API level 18 and above, get a reference to
    // BluetoothAdapter through BluetoothManager.
    final BluetoothManager bluetoothManager =
            (BluetoothManager) getSystemService(Context.BLUETOOTH_SERVICE);
    mBluetoothAdapter = bluetoothManager.getAdapter();
    
    // Checks if Bluetooth is supported on the device.
    if (mBluetoothAdapter == null) {
        Toast.makeText(this, R.string.error_bluetooth_not_supported, Toast.LENGTH_SHORT).show();
        finish();
        return;
    }
    //开启蓝牙
    mBluetoothAdapter.enable();
    
    mBLE = new BluetoothLeClass(this);
    if (!mBLE.initialize()) {
        Log.e(TAG, "Unable to initialize Bluetooth");
        finish();
    }
    //发现BLE终端的Service时回调
    mBLE.setOnServiceDiscoverListener(mOnServiceDiscover);
    //收到BLE终端数据交互的事件
    mBLE.setOnDataAvailableListener(mOnDataAvailable);
}

收到BLE终端数据交互的事件

/**
 * 收到BLE终端数据交互的事件
 */
private BluetoothLeClass.OnDataAvailableListener mOnDataAvailable = new OnDataAvailableListener(){

    /**
     * BLE终端数据被读的事件
     */
    @Override
    public void onCharacteristicRead(BluetoothGatt gatt,
            BluetoothGattCharacteristic characteristic, int status) {
        if (status == BluetoothGatt.GATT_SUCCESS) 
            Log.e(TAG,"onCharRead " gatt.getDevice().getName()
                     " read "
                     characteristic.getUuid().toString()
                     " -> "
                     Utils.bytesToHexString(characteristic.getValue()));
    }
    
    /**
     * 收到BLE终端写入数据回调
     */
    @Override
    public void onCharacteristicWrite(BluetoothGatt gatt,
            BluetoothGattCharacteristic characteristic) {
        Log.e(TAG,"onCharWrite " gatt.getDevice().getName()
                 " write "
                 characteristic.getUuid().toString()
                 " -> "
                 new String(characteristic.getValue()));
    }
};

最后给贴上Demo的源代码、希望对大家有用、有兴趣的哥们可以下载看看
