https://devzone.nordicsemi.com/f/nordic-q-a/72778/mesh-dfu-serial-transfer-of-dfu-archiveDear Nordic, I have a BLE mesh product that is in pre-production. The mesh gateway is composed of an nRF9160 and nRF52840 with a UART link connecting them. The nRF52840 in the gateway is the mesh client and services multiple nRF52840 mesh server nodesen-USTelligent Community 13Sun, 21 Mar 2021 20:27:00 GMThttps://devzone.nordicsemi.com/thread/301093?ContentTypeID=1Sun, 21 Mar 2021 20:27:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:436d381b-749e-4e6f-9bac-02652b40ed4bjkaye-du<p>Thank you Simon!

In (1) NCS us used on the nrf52840 and in (2) the nRF5 SDK is used on the nrf52840</p> <ol> <li><a href="https://github.com/plskeggs/sdk-nrf/tree/feature-uart-dfu-v1.4.0">https://github.com/plskeggs/sdk-nrf/tree/feature-uart-dfu-v1.4.0</a></li> <li><a href="https://devzone.nordicsemi.com/cfs-file/__key/communityserver-discussions-components-files/4/cross_5F00_dfu.zip">devzone.nordicsemi.com/.../cross_5F00_dfu.zip</a></li> </ol> <p>These project were not made with BLE Mesh in mind, so you probably have to modify them a little.</p> <p>Please get back to me if anything is unclear</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
