325

==== 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

350

351

If users want to test whether certificate writing works (without having valid certificates yet):

352

353

~1. Follow the same steps as above.

354

355

2. Check for success responses after each command:

356

357

358

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