build doesn't recognize zephyr files

[Raz_k]

Hello,

im trying to do the first exercise in DevAcademy (https://academy.nordicsemi.com/courses/bluetooth-low-energy-fundamentals/lessons/lesson-2-bluetooth-le-advertising/topic/advertising-process/) and i downloaded the relevent git aip file and opened a new project. its path is: C:\nordic\BLEexample\bt-fund\lesson1\blefund_less1_exer1

and my zephyr files are in : C:\ncs\v1.9.0\zephyr\include\sys\printk.h

the CMakeLists.txt are are as downloaded:

#

project(NONE)

# NORDIC SDK APP START
target_sources(app PRIVATE

)

# NORDIC SDK APP END

and i the build fails:
Building blefund_less1_exer1
west build --build-dir c:/nordic/BLEexample/bt-fund/lesson1/blefund_less1_exer1/build_1 c:/nordic/BLEexample/bt-fund/lesson1/blefund_less1_exer1

any idea why?

I am running into the same problem, which is good in a way. Then we know that this isn't really a symptom of there being anything wrong with your SDK.

However, when i build with the nRF52840DK_nrf52840 it is able to build and flash(using J-link) successfully.

So you do have a DK on hand as well?

The nRF9160 doesn't have BLE capabilities, so you shouldn't build anything in the BLE fundamentals course for that SoC. Another thing is that the Thingies (Thingy91 and Thingy53) might be a bit harder to work with. I would recommend using a development kit (DK) instead. For parhaps a better breakdown of the difference between the two, see here.

But im having trouble understanding how to test the program, since im connected via J-link and there is no outputs in the viewer app. In addition the device doesnt recognize my USB data cable.

Is this to the Thingy or the DK? The Thingy does not have an OB debugger, which might be the issue.
