Devices can use the following two methods to retrieve device certificates (ProductKey, DeviceName, and DeviceSecret) issued by IoT Platform: 1. Device manufacturers burn certificates on devices. 2. Devices retrieve certificates from the cloud after being powered on and connected to the Internet.

  • Burn device certificates

    Device manufacturers retrieve certificates issued by IoT Platform, and then use production lines to burn certificates on devices. After being powered on and connected to the Internet, devices use the certificates to access IoT Platform. The solution requires device manufacturers to transform production lines to burn certificates.

    For more information about this solution, see Burn certificates on devices.

  • Retrieve certificates from the cloud

    After being powered on and connected to the Internet, devices automatically retrieve the IP address, and connect to the cloud server of device manufacturers to retrieve certificates, and then connect to IoT Platform. During production, device manufacturers do not need to burn certificates on devices. This solution eliminates the need of certificate burning on production lines and speeds up the mass production of devices.
