Registering a Device (Verification Code Mode)
Typical Scenario
Before a device accesses the platform by using verification code, an application needs to call this API to register the device with the platform and set a unique identification code of the device (such as the IMEI) as the verification code. Then, the device can use the unique identification code to get authenticated and connect to the platform.
API Function
This API is used by an application to register a device with the platform. After registration, the device can connect to the platform.
API Description
1 | def regDirectDevice(self, rddInDto, appId, accessToken)
|
Class
DeviceManagement
Parameter Description
| Parameter | Mandatory or Optional | Type | Location | Description |
|---|---|---|---|---|
| rddInDto | Mandatory | RegDirectDeviceInDTO | body | For details, see RegDirectDeviceInDTO structure. |
| 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. |
RegDirectDeviceInDTO structure
| Parameter | Mandatory or Optional | Type | Location | Description |
|---|---|---|---|---|
| deviceInfo | Optional | Body | Specifies information about the device. | |
| endUserId | Optional | String(256) | Body | Identifies an end user. In the NB-IoT solution, this parameter is set to the IMSI of the device. In the Smart Home solution, this parameter is set to the application account. |
| imsi | Optional | String(1-64) | Body | Indicates the IMSI of an NB-IoT device. |
| isSecure | Optional | Boolean | Body | Indicates whether the device is secure. The default value is false.
NOTE: If a user needs to register a secure device, this parameter must be specified as true. |
| nodeId | Mandatory | String(256) | Body | Uniquely identifies a device. The value of this parameter must be the same as the device ID reported by the device. Generally, the MAC address, serial number, or IMEI is used as the node ID. NOTE: When the IMEI is used as the node ID, the node ID varies depending on the chip provided by the manufacturer.
|
| psk | Optional | String(8-32) | Body | If the pre-shared key (PSK) is specified in the request, the platform uses the specified PSK. If the PSK is not specified in the request, the PSK is generated by the platform. The value is a string of characters, including uppercase letters A to F, lowercase letters a to f, and numbers 0 to 9. |
| timeout | Optional | Integer(>=0) | Body | Indicates the validity period for device registration. When this API is called to register a device, the device can be bound within the validity period. If the device is not bound within the validity period, the registration information will be deleted. The value ranges from 0 to 2147483647. If this parameter is set to 0, the device verification code is always valid. (The recommended value is 0.) The default value is 0. The default value can be configured. For details, contact the platform maintenance personnel. Unit: second |
| verifyCode | Optional | String(256) | body | Specifies a unique device verification code. It is recommended that you keep the value of this parameter as the same as that of nodeId. If this parameter is specified in the request, it is returned in the response. If this parameter is not specified in the request, it is automatically generated by the platform. In the NB-IoT solution, this parameter is mandatory and must be set to the same value as nodeId. |
| productId | Optional | String(256) | Body | Identifies the product to which the device belongs. |
| Parameter | Mandatory or Optional | Type | Location | Description |
|---|---|---|---|---|
| manufacturerId | Optional | String(256) | Body | Uniquely identifies a manufacturer. |
| manufacturerName | Optional | String(256) | Body | Indicates the manufacturer name. |
| deviceType | Optional | String(256) | Body | Indicates the device type. The upper camel case is used, for example, MultiSensor, ContactSensor, and CameraGateway. |
| model | Mandatory | String(256) | Body | Indicates the device model. In Z-Wave, the format is productType + productId. The value is a hexadecimal value in the format of XXXX-XXXX. Zeros are added if required, for example, 001A-0A12. The format in other protocols is still to be determined. |
| protocolType | Optional | String(256) | Body | Indicates the protocol used by the device. The value options are CoAP, huaweiM2M, Z-Wave, ONVIF, WPS, Hue, WiFi, J808, Gateway, ZigBee, and LWM2M. |
Return Value
RegDirectDeviceOutDTO structure
| Parameter | Type | Description |
|---|---|---|
| deviceId | String(256) | Uniquely identifies a device. |
| verifyCode | String(256) | Indicates a verification code that can be used by the device to obtain the device ID and secret. If this parameter is specified in the request, it is returned in the response. If this parameter is not specified in the request, it is automatically generated by the platform. |
| timeout | Number | Indicates the validity period of the verification code, in seconds. The device must connect to the platform within this period. |
| psk | String(32) | Indicates a random PSK. If the PSK is carried in the request, this PSK is used. Otherwise, the platform generates a random PSK. |
