For flash operations from the application you should use the public API of the <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.meshsdk.v5.0.0%2Fgroup__FLASH__MANAGER.html">flash manager</a>, or use other API calls that will clear flash contents, such as e.g. <a href="https://infocenter.nordicsemi.com/index.jsp?topic=%2Fcom.nordic.infocenter.meshsdk.v5.0.0%2Fgroup__MESH__STACK.html&amp;anchor=gaabcc23d48f359c375ba3e89105c578c7">mesh_stack_config_clear()</a>.</p> <p>Regards,<br />Terje</p><div style="clear:both;"></div>
