NRF DFU Issue

[Siva]

Hi,

I am using "nRF Toolbox -> DFU" to change an application on my BLE module which contains; nRF52 device, SDK->v11.0.

I am using ".hex" file to load the application but it fails to upload. It seems that I am mising "Init.dat" file, I don't know how to generate one.

Could anyone suggest an advice on this issue.

Regards Siva

You need to create a firmware image zip as explained here.

Best regards

When I am trying to load ".Zip" file, it says "Upload Failed: DFU service not found". Am I missing Something here?

[bjorn-spockeli]

Have you flashed the bootloader, softdevice and an application that has DFU support to you nRF52 device?

I haven't uploaded bootloader, Could you please tell me how to create one.
