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

*Max number of WiFi dynamic TX buffers*

Type: ``int``

Help
====

.. code-block:: none

    Set the number of WiFi dynamic TX buffers. The size of each
    dynamic TXbuffer is not fixed, it depends on the size of each
    transmitted data frame.

    For each transmitted frame from the higher layer TCP/IP stack,
    the WiFi driver makes a copy of it in a TX buffer. For some applications,
    especially UDP applications, the upper layer can deliver frames faster
    than WiFi layer can transmit. In these cases, we may run out of TX
    buffers.
