228表示相机在当前状态不支持这个命令,所以在执行TAKE PHOTO之前要检查相机系统状态:
isTakingContinusPhoto
The state for identifying whether the camera would continuously take photo or not.
isTakingMultiPhoto
The state for identifying whether the camera would take multi-photos or not.
isTakingOnePhoto
The state for identifying whether the camera would take only one photo once or not.
