CONFIG_ISOTP_TX_BUF_COUNT
#########################

*Number of data buffers for sending data*

Type: ``int``

Help
====

.. code-block:: none

    Each data buffer will occupy CONFIG_NET_BUF_DATA_SIZE + smallish
    header (sizeof(struct net_buf)) amount of data. If context buffers
    are used, use the same size here.
