Tthe question about dfu via uart example.

[Eason huang]

Dears,

I'm using nrf52832 with PCA10040 and SDK 16.0.0,I want to make a DFU via uart.
So used the firmware provided in the SDK(nRF5_SDK_16.0.0_98a08e2\examples\dfu\secure_dfu_test_images\uart\nrf52832), then download softdevice_s132.hex, bootloader_secure_uart_debug_without_bonds_mbr.hex via nRFgo stdio.
Then use the "DFU using serial bootloader" to download hrs_application_s132.hex in nRFgo Studio.
However, it has been unable to download the application hrs_application_s132.hex.I don't know where something went wrong.can you please help me solve the questions?

Best regards,

Hi Eason, 

you cannot use nRFGo Studio to perform serial DFU with the bootloader from nRF5 SDK v16.0.0. You need to use the latest version of pc-nrfutil, found here: https://github.com/NordicSemiconductor/pc-nrfutil

You can download the latest release as a .exe file, see https://github.com/NordicSemiconductor/pc-nrfutil/releases. 

Best regards
