nrfutil.exe DFU via BLE

[Marcel]

I can successfully perform a DFU of my BLE device via the Nordic "nRF Connect" App using a nRF52 DK. I'm trying to do the same via nrfutil CLI, now running into an issue:

D:\Nordic Semi\nrfutil dfu ble -ic NRF52 -pkg app_dfu_package.zip -p COM4 -n "CA:91:ED:73:EF:DE" -f
Board already flashed with connectivity firmware.

What can be wrong here?

Hi, 

Are you using NCS or nRF5 SDK?

What is the nrfutil and python version you are using?

I must admit I do not recognize the error message, but I would suggest you use the latest version of nrfutil  which is tested wtih Pytnon 3.8. So I would also recommend you use that.

Hi Amadma, I can confirm that also with v6.1.7 this issue persists. What do you mean with NCS?

Hi, 

How do you generate the app_dfu_package.zip? Please post the commands you used to generate the app_dfu_package.zip. 

Could you run "nrfutil pkg display app_dfu_package.zip" and provid the log? Thanks.

Same issue.

Hi, 

Where do you get the app_dfu_package.zip? Are you using the nRF5 SDK or NCS?

nrfutil dfu ble only supports the package for nRF5SDK.
