Hi,
i have some issues with nrfutil, i can't properly perform an OTA DFU over thread, either nrfutil cannot find ncp.hex or it stuck in "thread DFU server is running..."
My setup is :
nrf52840 DK used as a server
arduino nano 33 ble sense used as a client
SDK 4.1.0 for thread and zigbee
commad usded : nrfutil dfu thread -f -pkg app_dfu_package.zip -p COM30 --channel 15 --panid 4369 (i use channel 15 and panid 0x1111 to perform ota dfu these parameters was changed in client code also).
in windows :
the first problem is when a used -f option to flash ncp.hex, nrfutil cannot locate the file and give me this error.

i was able to locate the file that have been used by nrfutil and i flashe it manualy and not use the -f option in the command; here also nrfutil does not perform OTA DFU an stuck in Thread DFU server is running as shown here:

i also try to do a multicast dfu but here the server start broadcasting and no client recieve the packages :

i install nrfutil manually and using pip install but i still have the same problem.
i hope i explain well the situation and i wish you could help us.
Best regards,
Ayoub.
