.. title:: BT_KEYS_SAVE_AGING_COUNTER_ON_PAIRING

.. option:: CONFIG_BT_KEYS_SAVE_AGING_COUNTER_ON_PAIRING

*Store aging counter every time a successful paring occurs*

Type: ``bool``

Help
====

.. code-block:: none

    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.
