Function now always rewrites old value under same key regardless existing data type. Users requiring old API behaviour can enable it by kconfig option CONFIG_NVS_LEGACY_DUP_KEYS_COMPATIBILITY

This option enables encryption for NVS. When enabled, AES-XTS is used to encrypt
|
|
the complete NVS data, except the page headers. It requires XTS encryption keys
|
|
to be stored in an encrypted partition. This means enabling flash encryption is
|
|
a pre-requisite for this feature.

bool "NVS partition encrypted flag compatible with ESP-IDF before v4.3"

help
|
|
Enabling this will ignore "encrypted" flag for NVS partitions. NVS encryption
|
|
scheme is different than hardware flash encryption and hence it is not recommended
|
|
to have "encrypted" flag for NVS partitions. This was not being checked in pre v4.3
|
|
IDF. Hence, if you have any devices where this flag is kept enabled in partition
|
|
table then enabling this config will allow to have same behavior as pre v4.3 IDF.

This option switches error checking type between assertions (y) or return codes (n).

help
|
|
Enabling this will switch the nvs_set family of functions to the legacy mode. When called with same
|
|
key and different data type, existing value stored in NVS remains active and as a side effect, the
|
|
new value is also stored into NVS, although not accessible using respective nvs_get function. Use only
|
|
if your application relies on this NVS API behaviour.
