328 -The -NB/-NS modules (BC660K) do not support clearing certificates via AT commands or firmware updates.

330 -To effectively remove existing certificates or test certificate upload functionality, users may overwrite them with dummy data.

333 -To effectively "clear" existing certificates, users may overwrite them with arbitrary data by following these steps:

335 -**Scenario A:** Clearing Existing Certificates

337 -1.Flash the certificate-provisioning firmware: **[[Set up TLS certificate - Dropbox>>https://www.dropbox.com/scl/fo/1ykfsesmr3702tj3kp663/AOOyH1GiVEOGR41gASuiDk0?rlkey=1q7a1b5yvjgt87d16w8tt0cum&st=vdy765ut&dl=0||data-sider-select-id="830d1b64-cb24-48b3-91e4-49da5c3f0783"]]**

339 -2. Use the standard AT commands (AT+CACERT, AT+CLICERT, AT+CLIKEY) to write non-certificate data (e.g., random strings like 123456).
