It is possible to use the procedure described in the<a href="http://developer.nordicsemi.com/nRF_Connect_SDK/doc/1.7.0/nrf/ug_nrf52.html"> FOTA upgrade section</a>&nbsp;to upload a new firmware directly on a mesh device. However, it is not guaranteed to be compatible with the DFU over mesh solution in the future. Please contact your regional sales manager for the&nbsp;<span>feature plan.&nbsp;</span></p> <p><span>Regards,<br />Amanda</span></p><div style="clear:both;"></div>
