https://devzone.nordicsemi.com/f/nordic-q-a/10045/debug-messages-through-puttyHello, I have been going through devzone questions to figure out how to enable the default debugging messages through Putty for the ble_app_proximity example project from the 0.9.2 SDK. These are a couple posts I have looked at to name a few: devzoneen-USTelligent Community 13Thu, 05 Nov 2015 01:05:24 GMThttps://devzone.nordicsemi.com/thread/37227?ContentTypeID=1Thu, 05 Nov 2015 01:05:24 GMT137ad170-7792-4731-bb38-c0d22fbe4515:1bbf7764-2440-4bef-9695-eff2b6a88f8fJudePinto<p>makes sense, thanks for the answer and explanation. Debug messages came out after i added it to the path. at first they were coming out as garbage, but once i programmed the softdevice correctly, the messages came out for the proximity app. So it works.

After you open the project go to Project -&gt; Options for target nrf51x22, you&#39;ll see the project properties, in that select C/C++ tab. In the &quot;Define:&quot; text box you can add this ENABLE_DEBUG_LOG_SUPPORT</p> <p>Defining in main.c will not work since the define doesn&#39;t get propogated to app_trace.h</p><div style="clear:both;"></div>
