Hi,

Please open a new case. Please check if you can communicate with the board via COM7 (test using uart example in the SDK), also make sure you flashed the connectivity firmware to be used with nrfutil.

Hi,

I also face a problem when trying to perform a DFU firmware update via command line using nrfutil dfu ble.

I'm using windows 10 and nrfutil.exe version 3.5.0

nrfutil dfu ble -ic NRF52 -pkg app_dfu_package.zip -p COM7 -n "DfuBoot_2018_07_18"

I am using for the PCA10040 EVB as connectivity device, the SOFTDEVICE ans SDK on my target device
are the same as was used by Fausto above.

@Fausto: You mentioned "The dongle is flashed with connectivity_1.2.0_115k2_with_s132_3.0". Could you tell a little bit more about the dongle ? was it a nRF51 chip or nRF52 chip ?

Have you tried to test DFU with just softdevice + bootloader ( no buttonless) ?

I just tested here with the same setup but didn't see any problem.

Thanks for the reply!

I'm using:

SDK 14.2.0
softdevice s132_nrf52_5.0.0_softdevice.hex
nrfutil 3.4

Hi,

Please provide more information on :

Which SDK and softdevice your bootloader using ?
Which nrfutil version you are using ?
