安卓正常，IOS调用notifyBLECharacteristicValueChange报10008错误，错误如下

"errCode":10008,"errno":1500104,"errMsg":"notifyBLECharacteristicValueChange:fail set notify failed. deviceID = 855209A6-28E7-109A-228F-103992E366CB, serviceID = 0000FF0F-0000-3000-8000-00805F9B34FB, characteristicID = 0000FFA1-0000-1000-8000-00805F9B34FB, errMsg = The value's length is invalid.

重启IOS手机后这个报错消失，notify正常，请问这个是什么原因造成的呢？
