49.8	325	==== 4.1.2.5 Certificate Management for -NB/-NS Models ====
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
49.13	336	1. [[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"]]
49.9	337
	338
49.13	339	2. Use the standard AT commands (AT+CACERT, AT+CLICERT, AT+CLIKEY) to write non-certificate data (e.g., random strings like 123456).
49.4	340	Example:
49.2	341
49.5	342	AT+CACERT=123456}
49.2	343
49.5	344	AT+CLICERT=123456}
49.3	345
49.5	346	AT+CLIKEY=123456}
	347
49.6	348	2. Upload Valid Certificates (Optional):
49.5	349
49.6	350	After overwriting, users may proceed to upload new valid certificates if needed.
