前言：关于Notification 和Indication  的区别，请见我另一篇帖子：（心情好了再写）

直接放代码：

开启Notification  ：

private boolean enableNotification(boolean enable,
			BluetoothGattCharacteristic characteristic) {
		if (mBluetoothGatt == null || characteristic == null)
			return false;
		if (!mBluetoothGatt.setCharacteristicNotification(characteristic,
				enable))
			return false;
		BluetoothGattDescriptor clientConfig = characteristic
				.getDescriptor(UUIDUtils.CCC);
		if (clientConfig == null)
			return false;
 
		if (enable) {
			clientConfig
					.setValue(BluetoothGattDescriptor.ENABLE_NOTIFICATION_VALUE);
		} else {
			clientConfig
					.setValue(BluetoothGattDescriptor.DISABLE_NOTIFICATION_VALUE);
		}
		return mBluetoothGatt.writeDescriptor(clientConfig);
	}
	
public final static UUID CCC = UUID
			.fromString("00002902-0000-1000-8000-00805f9b34fb");

开启Indication：

private boolean enableIndication(boolean enable,
			BluetoothGattCharacteristic characteristic) {
		if (mBluetoothGatt == null || characteristic == null)
			return false;
		if (!mBluetoothGatt.setCharacteristicNotification(characteristic,
				enable))
			return false;
		BluetoothGattDescriptor clientConfig = characteristic
				.getDescriptor(UUIDUtils.CCC);
		if (clientConfig == null)
			return false;

		if (enable) {
			clientConfig
					.setValue(BluetoothGattDescriptor.ENABLE_INDICATION_VALUE);
		} else {
			clientConfig
					.setValue(BluetoothGattDescriptor.DISABLE_NOTIFICATION_VALUE);
		}
		return mBluetoothGatt.writeDescriptor(clientConfig);
	}
