nRF5 SDK for Mesh v3.2.0  08c60f6
DFU example

This example is not supported by the nRF52810 Series.

This Device Firmware Update (DFU) example illustrates how to create an application that can be updated over the mesh using background mode DFU. In this mode, the new firmware is transferred in the background while the application is running and the DFU reports to the application when the transfer is done. The application can then flash the new firmware when ready.

More information about the DFU can be found in the Mesh DFU protocol section.
