48.2	326
	327
49.2	328	The -NB/-NS modules (BC660K) do not support clearing certificates via AT commands or firmware updates.
48.2	329
49.8	330	To effectively remove existing certificates or test certificate upload functionality, users may overwrite them with dummy data.
	331
49.2	332	To effectively "clear" existing certificates, users may overwrite them with arbitrary data by following these steps:
	333
49.9	334	Scenario A: Clearing Existing Certificates
49.2	335
49.9	336	If users want to remove old certificates:
	337
49.11	338	~1. Connect to the module via serial/USB and open a terminal (e.g., PuTTY, Tera Term).
49.9	339
	340
	341
49.4	342	Use the standard AT commands (AT+CACERT, AT+CLICERT, AT+CLIKEY) to write non-certificate data (e.g., random strings like 123456).
	343	Example:
49.2	344
49.5	345	AT+CACERT=123456}
49.2	346
49.5	347	AT+CLICERT=123456}
49.3	348
49.5	349	AT+CLIKEY=123456}
	350
49.6	351	2. Upload Valid Certificates (Optional):
49.5	352
49.6	353	After overwriting, users may proceed to upload new valid certificates if needed.
