==== 4.1.2.5 Clear Certificates by Overwriting (For -NB/-NS Modules) ====

326

327

328

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

329

330

To effectively remove existing certificates, users may overwrite them with dummy data.

331

332

333

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

334

335

**Scenario A:** Clearing Existing Certificates

336

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"]]**

338

339

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

Example:

AT+CACERT=123456}

AT+CLICERT=123456}

AT+CLIKEY=123456}

2. Check for success responses after each command:

351

352

[[image:1753772253801-330.png||height="495" width="620"]]

353

354

* If you get "Failure", retry or check module connectivity.

355

356

3. Later, when you have real certificates, overwrite the dummy data with actual certificates.
