Hello Arun,

I need a bit more information from you.

Which SDK are you using? 

Are you using a sample? If yes: which?

Are you flashing the file which is built for the DK?

Thanks.

Best regards,

Hi Maria, 

Which SDK are you using?
A. NRF Connect SKD v2.3.0 (MacOS)

Are you using a sample? If yes: which?
A. Samples from the “nrf5_sdk_for_thread_and_zigbee_v4.2.0_af27f76” folder

Are you flashing the file which is built for the DK?
A. Yes

I need help Regarding:
I want to know how to flash the nrf52840 Dongle. It’s not getting detected in the SDK in VS Code.
The only way to flash the dongle is through the “NRF PROGRAMMER Application”. And it only accepts “.hex” format files.
I just want to know how can I make my own custom program. (Especially) How to build a hex file of that program which the nRF52840 dongle accepts and runs. 

Thanks.
