Registering a Device (Verification Code Mode)

Updated at: Aug 28, 2019 GMT+08:00

Typical Scenario

Before a device accesses the IoT platform by using verification code, an NA needs to call this API to register the device on the IoT 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 IoT platform.

API Function

This API is used by an NA to register a device with the IoT platform. After registration, the device can connect to the IoT platform.

API Description

1
RegDirectDeviceOutDTO regDirectDevice(RegDirectDeviceInDTO2 rddInDto, String appId, String accessToken) throws NorthApiException

Class

DeviceManagement

Parameter Description

Parameter

Mandatory or Optional

Type

Location

Description

appId

Mandatory

String

query

If the device belongs to the current application, set this parameter to null. Otherwise, set this parameter to the ID of the authorized application.

accessToken

Mandatory

String

header

If the Periodically Refreshing a Token API is called, set this parameter to null. Otherwise, set this parameter to the accessToken obtained by the Authentication API.

rddInDto

Mandatory

RegDirectDeviceInDTO2

body

For details, see RegDirectDeviceInDTO2 structure.

RegDirectDeviceInDTO2 structure

Parameter

Mandatory or Optional

Type

Location

Description

deviceInfo

Optional

DeviceInfoDTO

Body

Indicates information about the device. For details, see DeviceInfo structure.

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.

  • true: The device is secure.
  • false: The device is not secure.
NOTE:

If a user needs to register a secure device, this parameter must be specified.

verifyCode

Optional

String(256)

body

Indicates the verification code of the device. 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 IoT platform.

In the NB-IoT solution, this parameter is mandatory and must be set to the same value as nodeId.

nodeId

Mandatory

String(256)

body

Uniquely identifies the 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.

  • The unique identifier of a Qualcomm chip is urn:imei:xxxx, where xxxx is the IMEI.
  • The unique identifier of a HiSilicon chip is the IMEI.
  • For details on the unique identifiers of chipsets provided by other manufacturers, contact the module manufacturers.

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 SmartHome solution, this parameter is set to the application account.

psk

Optional

String(8-32)

body

If the pre-shared key (PSK) is specified in the request, the IoT platform uses the specified PSK. If the PSK is not specified in the request, the PSK is generated by the IoT platform. The value is a string of characters, including upper-case letters A to F, lower-case letters a to f, and digits 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 180. The default value can be configured. For details, contact the IoT platform maintenance personnel.

Unit: second

productId

Optional

String(256)

Body

Identifies the product to which the device belongs.

DeviceInfoDTO:

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 type used by the device. The value options are CoAP, huaweiM2M, Z-Wave, ONVIF, WPS, Hue, WiFi, J808, Gateway, ZigBee, and LWM2M.

Return Value

RegDirectDeviceOutDTO

Parameter

Type

Description

deviceId

String(256)

Identifies a device.

verifyCode

String(256)

Indicates the device verification code, with which the device can get authenticated and connect to the IoT platform. 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 IoT platform.

timeout

Integer

Indicates the validity period of the verification code, in seconds. The device must connect to the IoT platform within this period. (If this parameter is set to 0, the verification code does not expire.)

psk

String(32)

Indicates a random PSK. If the PSK is carried in the request, it is used. Otherwise, the IoT platform generates a random PSK.
