Command Description
save This command moves any uploaded certificates or private keys to
permanent storage, making them persistent across restarts or
power cycles.
Issuing save after del-cert makes any certificate deletions
permanent.

The module is capable of storing multiple certificates. The number of certificates is
limited only by available resources; typically up to twenty (20) certificates can be held
by the module at any one time.
This allows multiple individual WPA2-Enterprise configurations to be applied to the
device server without needing additional certificates or private keys to be delivered to
the module.
