Over the Air Download (OAD)
===========================

This section serves as a guide to the Texas Instruments Over the Air Download
(:term:`OAD`) ecosystem including the profile, application architecture, drivers, and
middleware. :term:`OAD` allows the firmware image running on a BLE device to be updated
in the field without the need for wires or debuggers.

The guide will cover the princles of the :term:`OAD` process, the out of
the box demos included in the |SDK|, and the process for adding :term:`OAD` to an
existing project.


Scope
-----

The :term:`OAD` guide section will cover:

    - :term:`OAD` theory of operation
    - How to run the :term:`OAD` demos included in the |SDK|
    - How to add :term:`OAD` to an existing sample application

The supported development kit for :term:`OAD` is the |LP|.

.. warning::

    This guide assumes that both the :term:`OAD Target` and the 
    :term:`OAD Downloader` are running on the |LP|.
    Two |LP| devices are required to follow this guide.
