nvs save
Saves the active values of the parameters of a subsystem to NVS. This ensures
that these values will be used following the next reset.
cal option saves the calibration parameters
cfg option saves the configuration parameters for the specified subsystem
If the <set_name> option is used instead, only the named parameter will be
saved. Refer to the set command to determine available names.
If none of these options is specified, all of the calibration and configuration
parameters for the specified subsystem are saved.
When this command is entered, confirmation is requested. To continue with the
loading, type Y. To cancel, type N.
As an example, all drum subsystem parameters are saved by the following:
nvs save drum
To save only the calibration parameters for the drum subsystem:
nvs save drum cal
To save only the drum subsystem edge_position parameter:
nvs save drum epos
All
nvs save <subsys> [<index>] [cal|cfg|<set_name>]
