Because of that you may remove #if OPENTHREAD_ENABLE_DIAG condition from your main.c code, or you can add OPENTHREAD_ENABLE_DIAG define in the example Makefile.</p> <p>Thank you for reporting the issue which will be fixed in the upcoming release. All examples will call otDiagInit() function automatically.</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/118243?ContentTypeID=1Fri, 06 Oct 2017 14:24:50 GMT137ad170-7792-4731-bb38-c0d22fbe4515:05b75ca3-4f85-430e-8693-3500feff9a4fAtlas<p>The response is very slow.
