Creating a Software Upgrade Task

Typical Scenario

If the device software needs to be upgraded, an NA can call this API to create a software upgrade task for multiple devices. Before the upgrade, ensure that the target version package has been uploaded to the IoT platform. Currently, only the software of NB-IoT devices can be upgraded.

API Function

This API is used by an NA to upgrade the software of multiple devices on the IoT platform. Currently, only the software of NB-IoT devices can be upgraded.

Error Codes

HTTP Status Code	Error Code	Error Description	Remarks
400	120015	Bad request error.	A request error occurs. Recommended handling: Check whether the parameters in the request are correct.
400	123016	The parameter is error, targetversion not match with device.	The value of targetVersion is incorrect. Specifically, it does not match the specified device. Recommended handling: Check whether the values of deviceType, manufacturerName, and model carried in the API request are consistent with the target version package information specified by fileId.
400	123019	manufacturerName is null.	The manufacturer name is null. Recommended handling: Check whether manufacturerName carried in the API request is correct.
400	123020	deviceType is null	The device type is null. Recommended handling: Check whether deviceType carried in the API request is correct.
400	123021	model is null.	The device model is null. Recommended handling: Check whether model carried in the API request is correct.
400	123022	deviceGroups and devices cannot be null together	deviceGroups and devices cannot be both null. Recommended handling: Specify either deviceGroups or devices.
400	123023	deviceGroups and devices cannot be exist together	deviceGroups and devices cannot coexist. Recommended handling: Specify either deviceGroups or devices.
400	123024	The number of deviceGroups or devices reached upper limit	The number of device groups or devices reaches the upper limit. Recommended handling: Check the number of device groups or devices. The number cannot exceed 256.
400	123025	executeType is error or can not to be null.	The value of executeType is incorrect or is not specified. Recommended handling: Check whether executeType in the request is unspecified or incorrect.
400	123026	startTime or endTime is null or error.	The value of startTime or endTime is empty or incorrect. Recommended handling: Check whether startTime and endTime in the request are unspecified or incorrect.
400	123028	retryTimes is null or beyond the limit.	The value of retryTimes is empty or exceeds the upper limit. Recommended handling: Verify that the value of retryTimes in the request is left unspecified or is not less than 1 or greater than 5.
400	123032	startTime can not be later than the endTime.	The value of startTime cannot be later than the value of endTime. Recommended handling: Check whether startTime in the request is later than endTime.
400	123033	startTime can not be earlier than the now.	The value of startTime cannot be earlier than the current time. Recommended handling: Check whether startTime in the request is earlier than the current time.
400	123034	endtime must be greater than 5 minutes.	The value of endtime must be 5 minutes later than that of startTime. Handling suggestions: Verify that the interval between startTime and endTime in the request is greater than 5 minutes.
403	1010009	app throttle exceed.	The NA calls the API at a frequency that exceeds the flow control threshold (100 calls per minute by default). Recommended handling: Contact IoT platform maintenance personnel to adjust the flow control threshold or control the API call frequency.
