330 +To effectively remove existing certificates or test certificate upload functionality, users may overwrite them with dummy data.

330 330  To effectively "clear" existing certificates, users may overwrite them with arbitrary data by following these steps:
331 331  
332 332  1. Overwrite Certificates:
333 333  
336 +Use the standard AT commands (AT+CACERT, AT+CLICERT, AT+CLIKEY) to write non-certificate data (e.g., random strings like 123456).
337 +Example:
334 334  
339 +AT+CACERT=123456}
335 335  
341 +AT+CLICERT=123456}
336 336  
343 +AT+CLIKEY=123456}
344 +
345 +2. Upload Valid Certificates (Optional):
346 +
347 +After overwriting, users may proceed to upload new valid certificates if needed.
