CONFIG_BT_KEYS_SAVE_AGING_COUNTER_ON_PAIRING

Store aging counter every time a successful paring occurs

Type: bool

Help

With this option enabled, aging counter will be stored in settings every
time a successful pairing occurs. This increases flash wear out but offers
a more correct finding of the oldest unused pairing info.

Direct dependencies
