Creates a dynamic update batch.

Usage notes

  • You can specify that an update package does not need to be verified when you call the CreateOTAFirmware operation. Otherwise, you must make sure that the update package is verified before you call the CreateOTADynamicUpgradeJob operation to create an update batch. For more information about how to create a task to verify an update package, see CreateOTAVerifyJob.
  • Each device can be in the pending or updating state only in one update job. If you initiate another update task for a device that is in the pending or updating state, the update task fails.
  • Each update package can have only one dynamic update task that is in the running state.
  • If a device is included in dynamic update policies of different update packages, the device performs the latest dynamic update.
  • After a dynamic update batch is created, IoT Platform automatically creates the related dynamic update policy. You can call the CancelOTAStrategyByJob operation to cancel a dynamic update policy.

Limits

Each Alibaba Cloud account can run a maximum of 20 queries per second (QPS).

Note RAM users of an Alibaba Cloud account share the quota of the account.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates a sample code of the operation for different SDKs.

Request parameters

Parameter Type Required Example Description
Action String Yes CreateOTADynamicUpgradeJob

The operation that you want to perform. Set the value to CreateOTADynamicUpgradeJob.

FirmwareId String Yes nx3xxVvFdwvn6dim50PY03****

The ID of the update package.

An update package ID is returned when you call the CreateOTAFirmware operation to create the update package.

You can call the ListOTAFirmware operation and view the update package ID in the response.

ProductKey String Yes a1Le6d0****

The ProductKey of the product to which the update package belongs.

SrcVersion.N RepeatList Yes V1.0.1

The list of firmware versions to be updated.

Note
  • If you use a differential update package to perform dynamic update tasks, the value of this parameter must be the same as the value of the SrcVersion parameter.
  • You can call the QueryDeviceDetail operation and view the FirmwareVersion parameter in the response.
  • The version numbers must be unique in the list.
  • You can specify a maximum of 10 version numbers.
Tag.N.Key String Yes key1

The key of the update batch tag. The key must be 1 to 30 characters in length and can contain letters, digits, and periods (.). An update batch tag is sent to devices when IoT Platform pushes an update notification to these devices.

Note Update batch tags are optional. If you want to specify a tag, you must specify the Tag.N.Value and Tag.N.Key parameters in pair.
Tag.N.Value String Yes value1

The value of the update batch tag. The value must be 1 to 1,024 characters in length.

Note Update batch tags are optional. If you want to specify a tag, you must specify the Tag.N.Value and Tag.N.Key parameters in pair. The total tag keys and values cannot exceed 4,096 characters in length.
IotInstanceId String No iot-cn-0pp1n8t****

The ID of the instance.

You do not need to specify this parameter.

RetryInterval Integer No 60

The automatic retry interval if a device fails to be updated. Unit: minutes. Valid values:

  • 0: An automatic retry is immediately performed.
  • 10: An automatic retry is performed after 10 minutes.
  • 30: An automatic retry is performed after 30 minutes.
  • 60: An automatic retry is performed after 60 minutes (1 hour).
  • 1440: An automatic retry is performed after 1,440 minutes (24 hours).
Notice The value of the RetryInterval parameter must be less than the value of the TimeoutInMinutes parameter. Examples:
  • If the value of the TimeoutInMinutes parameter is set to 60, the maximum value of the RetryInterval parameter is 30.
  • If the value of the TimeoutInMinutes parameter is set to 1440, the maximum value of the RetryInterval parameter is 60.

If the value of the TimeoutInMinutes parameter is set to 1440, we recommend that you do not specify the TimeoutInMinutes parameter. If an update times out, no retry is performed.

If you do not specify this parameter, no retry is performed.

RetryCount Integer No 1

The number of automatic retries.

If you specify the RetryInterval parameter, you must specify this parameter.

Valid values:

  • 1: retries once
  • 2: retries twice
  • 5: retries five times
TimeoutInMinutes Integer No 1440

The timeout period of the update. If the device is not updated within the specified period, a timeout error occurs. Unit: minutes. Valid values: 1 to 1440.

Note
  • The timeout period starts from the time when the specified device submits the update progress for the first time. During the update, the update package may be repeatedly pushed to the specified device because the device goes online and offline multiple times. However, the start time of the update period does not change.
  • If an update fails due to timeout, no retry is triggered.

If you do not specify this parameter, timeout errors do not occur.

MaximumPerMinute Integer No 1000

The maximum number of devices to which the download URL of the update package is pushed per minute. Valid values: 10 to 1000.

Default value: 1000.

OverwriteMode Integer No 2

Specifies whether to overwrite the previous update task. Valid values:

  • 1: The previous update task is not overwritten. If a device already has an update task, the previous update task is implemented. This value is used by default.
  • 2: The previous update task is overwritten. Only the current update task is implemented.
Note The update task that is in progress is not overwritten.
DynamicMode Integer No 1

The mode of dynamic update. Valid values:

  • 1: constantly updates the devices that meet the conditions. This value is used by default.
  • 2: updates only the devices that subsequently submit the latest firmware versions.
NeedPush Boolean No true

Specifies whether to automatically push update tasks from IoT Platform to devices.

  • true: yes. After an update batch is created, IoT Platform automatically pushes update tasks to the specified online devices.

    In this case, a device can still initiate a request to obtain the information about the over-the-air (OTA) update task from IoT Platform.

  • false: no. A device must initiate a request to obtain the information about the OTA update task from IoT Platform.
NeedConfirm Boolean No false

Specifies whether to control the update by using a mobile app. You must develop the mobile app as needed.

  • false: no. A device obtains the information about the OTA update task based on the NeedPush parameter. This value is used by default.
  • true: yes. To perform an OTA update on a device, you must confirm the update by using your mobile app. Then, the device can obtain the information about the OTA update task based on the NeedPush parameter.

In addition to the preceding operation-specific request parameters, you must specify common request parameters when you call this operation. For more information, see Common request parameters.
