Modifying Device Information

Typical Scenario

After an NA registers a device with the IoT platform and the basic information about the device changes, the NA can call this API to modify device information on the IoT platform.

API Function

This API is used by an NA to modify the basic information about a device, including the device type, device model, manufacturer, and access protocol.

API Prototype

Method	PUT
URL	https://server:port/iocm/app/dm/v1.4.0/devices/{deviceId}?appId={appId}
Transport Protocol	HTTPS

Request Parameters

Parameter	Mandatory or Optional	Type	Location	Description
app_key	Mandatory	String	header	Identifies an application that can be accessed on the IoT platform. The value of this parameter is allocated by the IoT platform when the application is created on the platform.
Authorization	Mandatory	String	header	Indicates the authentication information for accessing the IoT platform. The value is Bearer {accessToken}, in which {accessToken} indicates the access token returned by the Authentication API.
deviceId	Mandatory	String	path	Uniquely identifies a device. The value of this parameter is allocated by the IoT platform during device registration.
appId	Optional	String	query	Identifies an application that can be accessed on the IoT platform. The value of this parameter is allocated by the IoT platform when the application is created on the platform. Set this parameter to the value of appId of the authorized application.

model	Optional	String(1~256)	body	Indicates the device model, which is defined by the manufacturer.
mute	Optional	String(1-256)	body	Indicates whether the device is in the frozen state. Based on the value of this parameter, the IoT platform determines whether to manage and store data reported by the device. TRUE: The device is in the frozen state. FALSE: The device is not in the frozen state.
name	Optional	String(1~256)	body	Indicates the device name.
organization	Optional	String(1~256)	body	Indicates the organization to which the device belongs.
protocolType	Optional	String(1~256)	body	Indicates the protocol used by the device. CoAP, LWM2M, and MQTT are supported.
region	Optional	String(1~256)	body	Indicates the region information about a device.
timezone	Optional	String(1~256)	body	Indicates the time zone of the device, for example, Asia/Shanghai and America/New_York.
imsi	Optional	String(64)	Body	Indicates the IMSI of an NB-IoT device.
ip	Optional	String(128)	Body	Indicates the device IP address.
isSecure	Optional	Boolean	body	Indicates whether the device is secure. The default value is false. In NB-IoT scenarios, if a registered device is an encryption device, this parameter must be set to true. true: The device is secure. false: The device is not secure.
psk	Optional	String(8-32)	body	Indicates the pre-shared key (PSK). 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.
tags	Optional	List<Tag2>	Body	Indicates the tag of a device.

CustomField structure

Parameter	Mandatory or Optional	Type	Location	Description
fieldName	Optional	String(256)	Body	Indicates the field name.
fieldType	Optional	String(256)	Body	Indicates the field type.
fieldValue	Optional	Object	Body	Indicates the field value.

DeviceConfigDTO structure

Parameter	Mandatory or Optional	Type	Description
dataConfig	Optional	DataConfigDTO	Indicates the data configuration information.

DataConfigDTO structure

Parameter	Mandatory or Optional	Type	Description
dataAgingTime	Optional	Integer[0,90]	Indicates the data aging time. The value range is 0–90. Unit: day.

Tag2 structure

Parameter	Mandatory or Optional	Type	Location	Description
tagName	Mandatory	String(1-128)	body	Indicates the tag name.
