Can we perform DFU on NCP?

[NM_Z]

Hi team,

We are using Raytech nrf52840 dongles as NCP connected through USB to RaspPi compute module. We would like to upgrade the NCP application in the field using DFU.

We thought of doing this through Rasp Pi using nrfutil commands but we were unable to do so due to support not available for arm.

Is there a way to upgrade the application on NCP in the filed? If yes, kindly share the details.

Thanks

NM

Hi, I enabled the DFU trigger library. But when I modified the application to enumerate the usb dfu trigger port. I get the error at nRF connect as "No DFU trigger interface found. Manually reset to bootloader mode"

Do you have any reference code for the application?
