##################################

*Maximum supported discardable HCI Event buffer length*

Type: ``int``

Help
====

.. code-block:: none

    Maximum support discardable HCI event size of buffers in the separate
    discardable event buffer pool. This value does not include the
    HCI Event header.
    The minimum size is set based on the Advertising Report. Setting
    the buffer size different than BT_BUF_EVT_RX_SIZE can save memory.

Direct dependencies
===================

\ :kconfig:`BT_HCI <CONFIG_BT_HCI>` && \ :kconfig:`BT <CONFIG_BT>`

*(Includes any dependencies from ifs and menus.)*

Defaults
========

- 255 if \ :kconfig:`BT_BREDR <CONFIG_BT_BREDR>` || \ :kconfig:`BT_EXT_ADV <CONFIG_BT_EXT_ADV>`
- 43
