nRF Toolbox: "Can not create Firmware"

[SoWizard]

I've started to get this error when trying to do a DFU update on nRF Toolbox (v5.0.8): "Can not create Firmware".

The same firmware file worked before on the same device that I'm trying to update. I have also tried it across different iOS devices and the issue persists.

Running the DFU update through nRF Connect for iOS, however, works completely fine. Could it be that some update to nRF Toolbox is causing this to happen?

Our stack is based on the old nRF5 SK, not the new nRF Connect SDK.

Hello,

This is an internal bug in the nRF Tool box Application. This has been already reported by my colleague here.

You need to use nRF Device Firmware Update App or nRF Connect app for doing the DFU in the mean time.

Kind Regards,
