Missing "nfc_t2t_lib.c" when building BLE Interactive example

[Wille]

When building example ble_app_interactive_s132_pca10040, SES asks for missing "nfc_t2t_lib.c" and "nfc_t2t_lib_al.c" files. This happens when SES is 'Preparing target for download', both in Debug and Release configurations. Specifically, it takes place just before SES reports successful download of SD hex.

I cannot find these files from the nRF5 SDK v17.0.0, where also the example project is. After clickcing cancel-no quite a few times*, SES eventually downloads the images to the device. However, it leaves me uncertain what's happening:

  1) What are these files?

  2) Are they essential by any means, reagarding how the compiled image works?

  3) How can I get rd of SES asking for the files?

I seem not be all alone with the observation, as HDuc has reported it as well (2+ years ago):

** EDIT **: *Irritatingly, the number of times it asks for file location is increasing all the time. It used to be ~6, then 18, now 24. Cleaning the solution does not help, neither reloading the project. How to deal with it?? This is becoming the major issue now.

Hello,

These warnings are safe to ignore. Uncheck the box and click "Yes" as shown below to prevent the message from popping-up every time you start a new debug session.

SES is basically looking for the proprietary source files that were used to build the pre-compiled nfc_t2t_lib_gcc.a library.
