*Number of outgoing ACL data buffers*

Type: ``int``

Help
====

.. code-block:: none

    Number of outgoing ACL data buffers sent from the Host to the
    Controller. This determines the maximum amount of data packets the
    Host can have queued in the Controller before waiting for the
    to notify the Host that more packets can be queued with the Number of
    Completed Packets event.
    The buffers are shared between all of the connections and the Host
    determines how to divide the buffers between the connections.
    The Controller will return this value in the HCI LE Read Buffer Size
    command response.
