dfu generate package using nrfutil cannot able update over the air

[NIDHIN K]

i am working nrf51822 and SDK V10 SoftDevice S110. I was using some old version of nrfutil ( dont know version ) to generate zip file, that was working fine.  when i start to using nrf52832 i updated nrfutil V6.0.1. I created zip file for nRF52 Board its also working fine. But now zip file created using this latest nrfutil for nrf51822 the zip file created successfully , but dfu not able to flash using nrfConnect app. i think its because nrfutil version issue. I cant able to install old version nrfutil.

How can able to generate dfu zip file using nrfutil v6.0.1 for nrf51822( SDKV10,S110) correct way ?

This is the error getting while updating dfu (for nrf51822 only). im not using key to generate dfu.

Hi,

As you can read here, nrfutil version 0.5.x generates legacy firmware packages compatible with nRF5 SDK v11.0.0 and earlier.

Link https://github.com/NordicSemiconductor/pc-nrfutil/tree/0_5_2

compiled exe: pc-nrfutil-0_5_2.zip

Example: 

nrfutil dfu genpkg --application APPLICATION.hex app.zip
