319 ==== 4.1.2.4 Re-upgrade the firmware ====
320
321
322 After completing the certificate configuration, Burn the [[bootloader>>https://www.dropbox.com/sh/u0uzvvnn58yrie4/AAAvvF_KRveNgmDejzp23ziLa/NB-IoT/Bootloader?dl=0&subfolder_nav_tracking=1]] firmware first, then re-burn the original working [[firmware>>https://www.dropbox.com/sh/u0uzvvnn58yrie4/AACREHllkTe0rATD4ZOqddyga/NB-IoT?dl=0]].
323
324
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).
340 Example:
341
342 AT+CACERT=123456}
343
344 AT+CLICERT=123456}
345
346 AT+CLIKEY=123456}
347
348
349 **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 * Expected output:
358
359 [[image:1753772253801-330.png||height="495" width="620"]]
360
361 * If you get "Failure", retry or check module connectivity.
362
363 3. Later, when you have real certificates, overwrite the dummy data with actual certificates.
