Can't select device in DFU mode using nRF Toolbox

[jm]

Hi all,

I have a question to complete the tutorial 'Setting up device firmware update(DFU) on the nRF5 DK'.this

I have tried to set up my nRF51 Development Kit. Everything was Ok, but when I look for my device in DFU mode using nRF Toolbox, I can't find my kit.

All devices are always 'n/a'. Should I change my device's name in uVision to detect it? Or is there anything else I need to do?

Please give me some advice.

Thank you in advance.

The DFU project is solely the bootloader. So if you mean you compiled the project and installed it then you would still need to load the SD130. Only the precompiled hex file I referred to has a complete image with SD and bootloader/dfu. As far as the error, not sure. Normally nRFGo just complains if the hex has code in already programmed space. Either way when you are programming it, you always best to start fresh and do and "erase all".
