https://devzone.nordicsemi.com/f/nordic-q-a/80064/dfu-dfu-using-ble-provision-erHi DevZone, I need help to understand the DFU procedure over the Mesh without any second BLE dongle/BLE serial device to populate the DFU packets. The ask is how can we populate DFU packets initialized by provisioning application over BLE Mesh. en-USTelligent Community 13Wed, 29 Sep 2021 01:21:10 GMThttps://devzone.nordicsemi.com/thread/331591?ContentTypeID=1Wed, 29 Sep 2021 01:21:10 GMT137ad170-7792-4731-bb38-c0d22fbe4515:bf94a688-10a3-4055-b120-d8225d900b1aPranjal Chanda<p>Hi,&nbsp;</p> <p>Yes your understanding is correct. We need to do the DFU transfer using mobile app.&nbsp;</p> <p>It can be similar to how we are doing DFU Point to point using BLE GATT.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/331515?ContentTypeID=1Tue, 28 Sep 2021 12:50:51 GMT137ad170-7792-4731-bb38-c0d22fbe4515:0211b5d2-4e14-4944-89dc-7c649065191aMttrinh<p>Hi,</p> <p>I&#39;m not sure I understand your question, do you want to know if you can do DFU over mesh without using a serial device(Like in our <a href="https://infocenter.nordicsemi.com/topic/com.nordic.infocenter.meshsdk.v5.0.0/md_doc_user_guide_modules_dfu_configuring_performing.html" rel="noopener noreferrer" target="_blank">DFU example</a>)? You want to do DFU over Mesh using a provisioner?&nbsp;</p> <p>Do you plan to do DFU via PC or an mobile applicaton?</p><div style="clear:both;"></div>
