I can't use nRF5 SDK 13.0.0 for nRF52840 DK board.

As the tittle. I load example in SDK 13 to nrf52840 DK but It does not generate bluetooth.

So poor description. Could you be more specific which part from nRF5 SDK you use with nRF52840 Preview DK, how, what do you expect to happen and what do you observe instead?
