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 +**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.
