nRF51822 DFU with nRF Toolbox iOS

[Masaya]

Hi,

Recently I updated nRF Toolbox iOS to 5.0.1.

I'm mainly using this tool for writing application via DFU to nRF51822 board.

I was using .hex files for DFU but I can't select .hex files when I 'm trying DFU in this version. .zip files are available.

My environment is legacy DFU. Secure DFU is not needed.

Does anybody tell me how can I write .hex files with nRF Toolbox iOS? or any other tools for achieving my purpose?

The legacy bootloader is not supported in the later versions of nRF Toolbox. I suggest that you check out the secure bootloader if you want to use the nRF Toolbox app. It adds a bit of security, and it really isn't that much more difficult than the non-secure one.

You can find the secure bootloader in SDK12.3.0\examples\dfu\bootloader_secure\pca10028

BR,

Hi Edvin,

Thank you for your answer.

I understand legacy DFU is not supported anymore with nRF Toolbox.

I will try secure bootloader.

Thanks,
