https://devzone.nordicsemi.com/f/nordic-q-a/43335/mesh-dfu-nrf52840-with-other-binary-fileHello everyone, I&#39;ve followed the following guide for mesh dfu and had no issues with the example provided here : https://www.nordicsemi.com/DocLib/Content/SDK_Doc/Mesh_SDK/v3-0-0/md_doc_getting_started_dfu_quick_start Now I would like to do the sameen-USTelligent Community 13Thu, 07 Feb 2019 13:46:26 GMThttps://devzone.nordicsemi.com/thread/169938?ContentTypeID=1Thu, 07 Feb 2019 13:46:26 GMT137ad170-7792-4731-bb38-c0d22fbe4515:86a12723-1a7a-4601-9b6e-cd6cd477c450qweqwe12<p>Hello,<br /><br />Your suggestion worked! I increased&nbsp;<span>SEND_START_DFU_WAIT_TIME&nbsp; to 3.0 and did not work, but Increasing it more to 5.0 did do the trick.&nbsp;<br /><br />Thank you</span></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/169763?ContentTypeID=1Wed, 06 Feb 2019 14:38:36 GMT137ad170-7792-4731-bb38-c0d22fbe4515:87300512-284b-4ba9-a258-e97316e0f4ebJoakim Jakobsen<p>Hello. <br />Sorry about the delay!</p> <p>Have you made any modifications to the client example you are using?</p> <p>I just tested this myself, and I worked without any problems.</p> <p>However, it might be that the erase sequence is taking too long.</p> <p>You could try increasing the t<span>ime to wait before communicating with bootloader after the start DFU packet is sent.<br />This is done by </span><span>increasing the SEND_START_DFU_WAIT_TIME in <a href="https://github.com/NordicSemiconductor/pc-nrfutil/blob/mesh_dfu/nordicsemi/dfu/dfu_transport_mesh.py#L148">dfu_transport_mesh.py</a>. (In the python source for nrfutil mesh branch).</span></p> <p><span>Try setting it to 3.0 first, and increase it even a bit more if that is not sufficient. The larger the application, the more you might have to increase it.</span></p> <p><span></span></p> <p><span>Let me know how that works out. </span></p> <p><span>Best regards, <br />Joakim Jakobsen</span></p><div style="clear:both;"></div>
