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.
