Hi,

Which project are you using, and what device are you talking about? I can only see link to a header file to the Board Support Package in your post.

The ICs are shipped without any bootloader/firmware. DFU bootloader examples can be found in the SDK in examples\dfu directory.

Best regards,
Jørgen

sorry i am using this project,

\nRF5_SDK_14.2.0_17b948a\nRF5_SDK_14.2.0_17b948a\examples\ble_central\ble_app_uart_c\

why ic is shipped without any bootloader /firmware?  the origin image is not available ? if i  need a bootloader, i must  complie and use dfu bootloader ? but i think to center device,it can not be searched by nrf connect.i do not need dfu bootloader ,is it true ? dfu is only fit to client.

Customers will flash their own examples, therefor the ICs come with blank flash. The firmware that the DKs are shipped with is available in the SDK.

If you want to use bootloader, you need to compile and flash it yourself.
