.. title:: BT_MESH_MSG_CACHE_SIZE

.. option:: CONFIG_BT_MESH_MSG_CACHE_SIZE

*Network message cache size*

Type: ``int``

Help
====

Number of messages that are cached for the network. This helps
prevent unnecessary decryption operations and unnecessary
relays. This option is similar to the replay protection list,
but has a different purpose.
