iOS MSDK 4.14
无人机：M300和御2
在调用设置固定低电量阈值，无人机自动返航的接口时报错。错误：Current product does not support this feature.(code:-1013)
调用接口：- (void)setLevel1CellVoltageThreshold: (NSUInteger)voltage withCompletion: (DJICompletionBlock)completion;

           - (void)setLevel1CellVoltageBehavior: (DJIBatteryLowVoltageBehavior)behavior withCompletion: (DJICompletionBlock)completion;

请问是无人机不支持相关操作吗
