Bootstrap Device¶

Bootstrap Device API is used by the device to get its triple information and the EnOS MQTT/HTTP protocol public address. After obtaining the triple information using this API, the device can use the EnOS-provided device SDK to attempt a connection to EnOS.

Bootstrap Device API is compatible with Get Device Connection Info, with the following differences:

API Name	Function	Scenario Sample
Get Device Connection Info	Registered devices to get the triple information, including single-channel devices, multi-channel devices, gateway devices, and sub-devices.	Registered devices get the triple information for themselves, branch devices, or sub-devices.
Bootstrap Device	Direct-connected devices to get their own triple information and register themselves if they are unregistered.	Direct-connected devices register themselves.

Request Format¶

POST http(s)://{dps-address}/2.4.4/bootstrap

For more information, see About Device APIs.

Request Parameters (Header)¶

Name	Required/Optional	Data Type	Description
Content-type	Required	String	The content or file type. Supports `application/json` only.

Request Parameters(Body)¶

Name	Required/Optional	Data Type	Description
deviceSn	Required	String	Device Serial No., which is unique in the registration group.
groupId	Required	String	The ID of the registration group which the device belongs to.
dpsSignMethod	Required	String	The signature algorithm. Supports `sha256` only.
dpsSignTimestamp	Required	Long	The timestamp to generate the verification value in the `dpsSign` parameter.
dpsSign	Required	String	The verification value that is generated by SHA256 algorithm based on the registration group password, `deviceSn`, and `dpsSignTimestamp` as inputs. You can find the registration group password in EnOS Management Console > Device Provisioning > Registration Group Management.
deviceName	Required	StringI18n	The device name. Internationalized name representation >>
timezone	Required	String	The timezone of the device. Timezone representation >>

Response Parameters¶

Name	Data Type	Description
murl	String	The EnOS MQTT protocol public address for the device’s environment.
hurl	String	The EnOS HTTP protocol public address for the device’s environment.
pk	String	The product key in the triple information of the device.
dk	String	The device key in the triple information of the device.
ds	String	The device secret in the triple information of the device.

Error Codes¶

Code	Message	Description
10000	[{sn}] not allocated	If the device is unallocated and the “Auto Activation” of the registration group is not enabled, the triplet cannot be obtained and an error message indicating the device is unallocated will be returned.
