Creates a dynamic update batch.

Limits

  • When you call the CreateOTAFirmware API operation to create an update package, no verification is required for the update package. However, before you call the CreateOTADynamicUpgradeJob API operation to create an update batch, make sure that the update package is verified. For more information, 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 API operation to cancel a dynamic update policy.
  • 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 the 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. The ID is the unique identifier for the update package.

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

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

ProductKey String Yes a1Le6d0****

The key of the product to which the update package belongs.
Tag.N.Key String Yes key1

The key of each update batch tag. The key can contain letters, digits, and periods (.). The name must be 1 to 30 characters in length. 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 specify update batch tags, you must specify a value and key for each update batch tag.
Tag.N.Value String Yes value1

The value of the update batch tag. The value must be 1 to 128 characters in length.

Note Update batch tags are optional. If you specify update batch tags, you must specify a value and key for each update task tag.
IotInstanceId String No iot-cn-0pp1n8t****

The instance ID. This parameter is not required for public instances. However, the parameter is required for the instances that you have purchased.

SrcVersion.N RepeatList No V1.0.1

The list of firmware versions to be updated.

Note
  • When 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 API operation to view the FirmwareVersion parameter in the response.
  • The list cannot contain duplicate versions.
  • A maximum of 10 versions can be specified.
RetryInterval Integer No 60

The automatic retry interval after 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).

If you do not specify this parameter, no retry is performed.
RetryCount Integer No 1

The number of automatic retries.

You must specify this parameter if you specify the RetryInterval parameter.

Valid values:

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

The timeout period for a device update. Unit: minutes. Valid values: 1 to 1440.

If an update is not completed after the specified timeout period, the update fails.

Note
  • The timeout period starts from the time when the specified device submits the update progress for the first time.
  • If an update fails due to a timeout issue, no retry is triggered.
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.

If you do not specify this parameter, the default value 1000 is used.
OverwriteMode Integer No 2

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

  • 1: do not overwrite. If a device already has an update task, the previous update task is implemented.
  • 2: overwrite. Only the current update task is implemented.

If you do not specify this parameter, the previous update task is not overwritten by default.

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.
  • 2: updates only the devices that subsequently submit the latest firmware versions.

If you do not specify this parameter, the default value 1 is used.

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