| Overview |
| ******** |
| |
| A simple protocol buffer sample using :ref:`nanopb_reference` for serializing structured data |
| to platform independent raw buffers or streams. |
| |
| The structured data to encode/decode is presented as follows: |
| |
| .. code-block:: proto |
| |
| syntax = "proto3"; |
| |
| message SimpleMessage { |
| int32 lucky_number = 1; |
| bytes buffer = 2; |
| int32 unlucky_number = 3; |
| } |
| |
| Configuration |
| ************* |
| |
| This sample uses two configuration options to modify the behavior. |
| |
| * :kconfig:option:`CONFIG_SAMPLE_BUFFER_SIZE` sets the ``buffer`` field's size |
| * :kconfig:option:`CONFIG_SAMPLE_UNLUCKY_NUMBER` either enables or disables the ``unlucky_number`` |
| field. |
| |
