Cellular Monitor - modem credentials management

You can store and update modem credentials, such as keys or certificates, manually by sending Credential storage management %CMNG commands to the modem. The certificate manager simplifies this process by offering a graphical user interface for updating credentials.

Before you can update the credentials stored by the modem, you must put the modem into the offline state by sending the AT+CFUN=4 AT command.

Each set of keys and certificates that is stored in the modem is identified by a security tag. This means that all related credentials share the same security tag. Send the AT%CMNG=1 command in the terminal view to display a list of all certificates that are stored on your device. If you have added your device in nRF Cloud, you should see a Certificate Authority (CA) certificate, a client certificate, and a private key with security tag 16842753 which is the security tag for nRF Connect for Cloud credentials.

The credentials can be managed in the following ways.

To add or update credentials, enter a security tag and the new keys or certificates. Then click Update certificates.
Instead of entering the credentials manually, you can also import a JSON file. To do so, click Load from JSON.
To delete a key or certificate, select the checkbox next to it. Then click Update certificates.

Note: Deleting the text from the text field does not cause the key or certificate to be unset.
