Device Information
This section outlines device information on the "Device Maintenance" page, including basic information and module information.
Prerequisites
● A product is created.
● The steps from Define Feature to Debug Device have been completed.
Procedures
1.Log in to Developer Center and select "Device Maintenance" from the "Device Management" drop-down box in the left-hand menu bar. Once you are on the "Device Maintenance" page, click "View" in the "Action" column to navigate to the "Device Information" tab.
Basic Information
| Parameter | Description |
|---|---|
| Associated Product | Name of the product to which the device is associated |
| Device Status | Online/Offline |
| Device Name | The default value is the same as DeviceKey. It can be edited. |
| DeviceKey | DeviceKey is the customized unique identifier for devices under a product used for connecting to Development Center. |
| DeviceSecret | DeviceSecret is issued by Developer Center after the device is certificated |
| Authentication Type | Authentication type when the device accesses Developer Center. |
| Certificate Fingerprint | Device certificate identifier, which is used to verify the connection permission of the device. After a successful bidirectional authentication between the device and Developer Center, the certificate fingerprint will be bound to the device. Subsequent connections to Developer Center can only be made by using this device certificate. To calculate the device certificate fingerprint, use SHA-1 hashing, such as openssl x509 -fingerprint -sha1 -in certfile.crt. The fingerprint generated by OpenSSL includes colons ":" and must be converted to a 40-bit hexadecimal string without the colons before uploading. To update the device certificate fingerprint, you can reset the fingerprint and set a new value. Once the new fingerprint is set successfully, the device can use it to authenticate with Developer Center. |
| Device Type | Directly Connected Device, Gateway, Gateway sub-device |
| Connection Protocol | Protocol used by the device to connect to Developer Center. MQTT and LwM2M are currently supported. |
| Creation Time | The time when the device is added to Developer Center |
| Previous Online Time | The last time the device was online |
| Device SN | ID of the device bound to App. It can be edited. |
