Setting up device firmware update(DFU) on the nRF5 DK

[asusss]

The goal is that we can update the firmware version with the smartphone or tablet without having
need to go through the development tools
(cable, IDE, ...)
if so, how can I do it

Hi,

Our SDK includes examples to demonstrate how you can perform over-the-air updates, please take a look at this blog post to get started: https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/getting-started-with-nordics-secure-dfu-bootloader

Hello everyone,
I combined sd.hex, settings.hex, dfu.hex (3 files combined) and programmed it via nrfjprog. Then, I could see that DFU was enabled in the application and I was able to load the app.hex via the application nrfconnect. But once I made a DFU via Bluetooth with app.hex and restarted the device, the DFU mode was disabled.

Can someone help me please about this?
