Cirrent supports dynamic provisioning of devices, where you can use a provisioning key that is shared across many devices. Cirrent's service uses this provisioning key and the device id to generate a temporary shared secret unique to the device, and uses that to log into ZipKey hotspots and the Cirrent cloud. On the first connection, the device is then issued a more permanent device id and shared secret, which the device uses from that time forward.
Here is how you configure the WCM to use the temporary credentials:
- Make sure you have a Provisioning Key (learn more here)
- Download the credential generator source code from https://github.com/Cirrent/wcm-credential-generator
- Edit main.c to add your provisioning key and secret, and set your device type id and account id. You can get your device type from the Management Center and your account id here.
- Compile the credential generator executable
- Run the credential generator executable on the device, passing in the path to the temporary credential file.
sudo ./wcm_credential_generator -c /etc/wcm/keys/temporary.key
- Set the Temporary Credentials flag in the wcm_agent.conf file.
When the WCM starts, it will read the temporary credential file and use the temporary credentials to log in to ZipKey network. As soon as the WCM can reach the cloud, WCM will get new permanent credentials for the device. You can check that this happened correctly by looking at the Management Center where you should see a new device id, using the MAC address for your device.
