Values representing the possible properties of a characteristic. Since characteristic properties can be combined, a characteristic may have multiple property values set.
1.read，调用readValueForCharacteristic方法，然后数据更新的时候会调用peripheral:didUpdateValueForCharacteristic:error:方法。此时读取value值即可。
2.write，使用 writeValue:forCharacteristic:type:方法写数据。type值表明是否有response。（没有response的比有response的数值可以更长？）
