Hi

These errors point towards these files not being added corectly to your project. Have you downloaded the nRF5 SDK v16.0.0 and added the nRF Calendar example to the /examples/peripheral/ folder?

Please also make sure that these files are included to your project. If you're not sure how to do this, please tell me which IDE you're using, and I'll show you how.

Best regards,

Simon

Hi

This has been asked quite a few times previously on the DevZone, please check out this thread where my colleague and another DevZone member explain this in detail. You can also check out this thread for alternatives to epoch.

Best regards,
