Querying Device Activation Status
Typical Scenario
After an application registers a device on the platform, the activation status of the device is false before the device connects to the platform for the first time. When the device connects to the platform for the first time, the activation status of the device is true regardless of whether the device is online, offline, or abnormal. The application can call this API to query the activation status of the device to check whether the device has connected to the platform.
API Function
This API is used by an application to query the activation status of a device on the platform to determine whether the device has connected to the platform.
API Description
1 | def queryDeviceStatus(self, deviceId, appId, accessToken)
|
Class
DeviceManagement
Parameter Description
| Parameter | Mandatory or Optional | Type | Location | Description |
|---|---|---|---|---|
| deviceId | Mandatory | String | path | Identifies a device. The device ID is allocated by the platform during device registration. |
| appId | Optional | String | query | If the device belongs to the current application, set this parameter to None. Otherwise, set this parameter to the ID of the authorized application. |
| accessToken | Mandatory | String | header | This parameter is set to the value of the accessToken obtained by calling the Authentication API. |
Return Value
QueryDeviceStatusOutDTO structure
| Parameter | Type | Description |

| deviceId | String(256) | Uniquely identifies a device. |
| activated | Boolean | Indicates whether the device is activated through a verification code.
|
| name | String(256) | Indicates the name of the device. |
Error Codes
| HTTP Status Code | Error Code | Error Description | Remarks |
|---|---|---|---|
| 403 | 100203 | The application does not exist. | The application does not exist. Recommended handling:
|
| 403 | 100217 | The application has not been authorized. | The application has not been authorized. Recommended handling: In scenarios where applications are not authorized, ensure that request parameter appId is null. |
| 403 | 1010009 | The application calls the API at a frequency that exceeds the flow control threshold. | The application 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. |
| 403 | 1010005 | Invalid access token or application ID. | The access token is invalid. Recommended handling: Check whether accessToken carried in the API request is correct. |
