Which SDK and SoftDevice version are you using? Is this for the nRF51 or the nRF52? When specifically does the error occur during the DFU process?

Hi Bjorn,

I am using nRF51822_AC, SDK 6 and S120. After Opening DFU in nRF Toolbox and browse application binary file and select device then i found "unsupported DFU" erro on screen.

Thanks Bipin Patel

Which version of the nRF Toolbox app are you using? I think you have to provide a hex file and not a bin file.
