Hi Vasilje,
Please confirm that you DFU update the application: ble_central/ble_app_gatts

If it's the case it's normal that it doesn't advertise. It's a central application. So it's not expected to advertise but to scan and connect. Please have a look at the documentation here.
Please try to test again with ble_peripheral example, for example ble_app_hrs.

Hey, thanks for the answer. I am using nRF5 SDK 17.0.2. Maybe my question was misunderstood. I am able to flash the program with DFU (I sucessfully set up open_bootloader) but for some reason the application didnt behave as I expected. So I was just wandering about the ways to debug application after it was successfully flashed with DFU.

Hi,

What SDK and SDK version are you using? In nRF5 SDK v17.0.2 there is an open bootloader project for the PCA10056 already that you can use directly.

Note also that before you can do a DFU, you must program the DFU bootloader on the DK. What you describe is performing DFU (nrfutil dfu usb-serial -pkg dfu.zip -p /dev/ttyACM0.) In order to put a bootloader on the board in the first place, you should program the SoC with nrfjprog.

Regards,
Terje
