Are you using two nRF52 DKs, i.e. one for the connectivity board connected to your pc and one that is the DFU target?

[christ]

Thank you for help. I retry to test. pc connected to board only one. other devices are power off.

D:\nordic_nrf52832>nrfutil.exe dfu ble -ic NRF52  -f -pkg dfu_test_app_hrm_s132.zip -p COM8 -n "DfuTest" -f

Ok, that is expected if the DFU Target is powered off. Can you try to run the command promt as administrator and then try to perform a DFU with both devices powered on?

Hello!

I'm having the same issue and couldn't find a thread on the forum that actually answers the question.

I have a nRF52840 dongle connected to COM6 which is able to DFU my nrf52832 device without problem. 

But when i try to perform  DFU from command line (running windows 10). I get the same error as in the original issue above. The command I use is:

nrfutil dfu ble -ic NRF52 -pkg dfu_package.zip -p COM6 -a "E5:15:E0:5E:E9:82"

I have also tried using the MAC address for the 832 when it is in DFU mode and I have also tried using -n "DeviceName" where the name I use is the same that is displayed in nRF Connect instead of the -a flag. 

This is the error I get:

Hi Berrag, 

It should be possible to perform DFU with nrfutil and the nRF52840 Dongle, see https://devzone.nordicsemi.com/f/nordic-q-a/39630/windows-command-line-dfu-over-ble-with-pca10059. 

Is the nRF52840 Dongle programmed with the connectivity firmware ? It should be listed as  USB: Nordic Semiconductor nRF52 Connectivity in nRF Connect for desktop: Bluetooth Low Energy application.

Also which version of nrfutil  and which version of the SDK are you using? 

Best regards 

Bjørn
