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.

Thank you for your quick reply. Did you mean I don't need to download the project if I use the precompiled hex file (you referred to)?

Then, is the following procedure correct in nRFgo Studio?

1.Device Manager->nRF5x Programming->Erase all

2.Device Manager->nRF5x Programming->(Program Application tap) select that hex file->Program

And does this procedure make the device show up as DfuTarg? Because I followed above procedure, but I can't find my device. Please advise whether there is a problem in the procedure or an unexpected error.
