*GDB backend send/receive buffer size (in bytes)*

Type: ``int``

Help
====

.. code-block:: none

    This specifies the size (in bytes) of the send/receive buffer
    for GDB backend. This needs to be big enough to hold one
    full GDB packet at a time.

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

(\ :kconfig:`GDBSTUB <CONFIG_GDBSTUB>` && \ :kconfig:`SOC_ESP32 <CONFIG_SOC_ESP32>`) || \ :kconfig:`GDBSTUB <CONFIG_GDBSTUB>`

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

Defaults
========

- 840 if \ :kconfig:`GDBSTUB <CONFIG_GDBSTUB>`
- 256
