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.

JM, yes if you use the precompiled hex you do not need to download the project. It is ready to go and the image includes the SD. Once loaded your DK will go straight into dfu mode.

If it doesn't go into dfu mode then you are either loading the wrong file, or do not have an nRF51DK. You should verify both the model of your DK and the file name precisely! Many of the files have similar names but are not similar at all.

The file is: dfu_dual_bank_ble_s130_pca10028.hex

Your dk should be model# pca10028

@Hung Bui Thank you for your comment. Unfortunately, I'm using SDK v10. However, I think that tutorial might be useful to understand the procedure for implementing bootloader. Thank you so much!

@AmbystomaLabs Thank you very much for your kind answers. I seem to have a lot of silly questions because of lack of knowledge. I have not solved it yet, but I'll continue to try it based on your advice. Best,

I'm glad I could help out. Please let me know how it works out.
