Hello, I've a "DA14580 Development Kit - Pro" and I've just run the blinky demo built with Keil uVision V5.26.2.0 (so far so good...).
I tried to test Bluetooth connectivity, so I launch a built of the project for the "prox_reporter_580" target but I get an error:


linking...
.\out_580\prox_reporter_580.axf: error: L6002U: Could not open file .\..\..\..\..\..\sdk\platform\patch_code\DA14580\obj\atts_task.obj: No such file or directory
Not enough information to produce a FEEDBACK file.
Finished: 1 information, 0 warning, 0 error and 1 fatal error messages.
".\out_580\prox_reporter_580.axf" - 1 Error(s), 1 Warning(s).
Target not created.


How can I solve that?

If I enter debugging despite the error, the debug start on my board (I see the activity onm the red led too, not only the debug GUI that is running) but the bluetooth device is not visible neither to my Android phone (Huawey P9 Lite) nor to my laptop (NO USB DONGLE, native Bluetooth periferal: it's an ASUS N56JN).

What's happening?
Where can I find an updated documentation in order to run the examples on my board?

Thank you very much indeed in advance,
Maurizio
