Generating a certificate

You can use the CLI to generate a certificate for your device. The firmware will use the IMEI of the device as the MQTT client ID. You can get the IMEI of your device using the AT command AT+CGSN. The IMEI is also typically printed on a sticker on the device.

Following is the output of the command:

# AT+CGSN
352656100248049 OK

Use the IMEI when generating the certificate:

 node cli create-device-cert -d "imei"

Note

The default lifetime for device certificates is 30 years. Run node cli create-device-cert --help to learn how to customize the lifetime.
