Hi,

The DFU bootloader is a separate project from the main application, as it is a separate piece of software to be put on the SoC. (Just as the SoftDevice is separate from the application.) What you may want to merge with the ble_app_uart_project, is the functionality from the buttonless DFU example, which enables the application to reset the device in such a way that the DFU bootloader enters DFU mode (allowing for DFU to happen.)

For an overview of how our DFU solution works, please have a look at getting started with Nordic's Secure DFU bootloader, a step by step guide. When you have a thorough understanding of the DFU process and have tested that out, you can have a look at the Buttonless DFU appendix for how DFU mode can be triggered from the application.

Regards,
Terje
