do you have a user gide for Serial DFU just like buttonless DFU ,like this link https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/getting-started-with-nordics-secure-dfu-bootloader#h61sjziauupw1j397q9s9ldr01q4j6d5?

Hi Roger, 

Could you explain what exactly you need ? 
If you are looking for how to do serial DFU, you can follow the guide until Step D, and then follow this: https://infocenter.nordicsemi.com/index.jsp?topic=%2Fug_nrfutil%2FUG%2Fnrfutil%2Fnrfutil_dfu_serial.html

If you are looking for UART DFU buttonless, we currently don't have an example for that, but you can just follow what we do in the BLE DFU buttonless, and define your own protocol to trigger the DFU process.
