Buttonless DFU for nrf52833

[Shweta]

I want to implement Buttonless DFU for nrf52833 but unable to get how to implement it. I have gone through some links but that seems to be unclear. How can I implement the same?

Any tutorial, links, or anything will be appreciated.

yes i am using the development kit nRF5340-DK for debugging.

Then I suggest you go over the connections to find out why the on-board nRF5340 is being programmed instead of your external nRF52833 target. The SWD signals will be routed to the debug out headers when voltage is applied on VTG.
