If the same applications work on the DK, but not the dongle, then it's a bit difficult to find the root cause without doing some debugging. To debug the dongle, it's possible to use the debugger on the DK, and connect that to the dongle.

Either like this if you have 10-pin cable:

or like this with wires:

Did you connect a arducam to the dongle?

I tested the blinky example inside the same application file and it worked. Then I strongly believe that the code somehow crashes but in the DK it works fine.

I used s140 as a soft device just like in the Dongle and add the application afterward but nothing changed.

Maybe you didn't flash the SoftDevice to the dongle ?

In the DK it's working fine actually. But whenever I write into the dongle, it successfully loads but advertising did not started

Hi,

I would assume that the same application crashes on the DK as well then. Maybe you can try debugging the application on the DK.
