I am trying to save the MAC address and UUID through UART, so I don&#39;t know what to do.

See the documentation <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.meshsdk.v5.0.0/md_doc_user_guide_modules_flash_manager.html?cp=8_2_2_4_1">here</a>.&nbsp;</p> <p>regards</p> <p>Jared&nbsp;</p><div style="clear:both;"></div>
