==== 4.1.2.5 Certificate Management for -NB/-NS Models ====

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 or test certificate upload functionality, 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}

**Scenario B:** Testing Certificate Upload Functionality

349

350

2. Upload Valid Certificates (Optional):

351

352

After overwriting, users may proceed to upload new valid certificates if needed.
