https://devzone.nordicsemi.com/f/nordic-q-a/18848/visualgdb-beacon-sample-nrf51422Hi, I wonder where and how to define NRF_CLOCK_LFCLKSRC using the VisualGDB Beacon sample using VisualStudio with VisualGDB. The sample includes #include &lt;stdbool.h&gt; #include &lt;stdint.h&gt; #include &quot;ble_advdata.h&quot; #include &quot;nordic_common.h&quot; #includeen-USTelligent Community 13Sun, 08 Jan 2017 05:12:46 GMThttps://devzone.nordicsemi.com/thread/72805?ContentTypeID=1Sun, 08 Jan 2017 05:12:46 GMT137ad170-7792-4731-bb38-c0d22fbe4515:82b53eff-ee14-466e-889f-5debde59fd4cMikkael<p>I just had to add this code in my main.c to make it work:</p> <pre><code>#define NRF_CLOCK_LFCLKSRC{ .source = NRF_CLOCK_LF_SRC_RC, \ .rc_ctiv = 16, \ .rc_temp_ctiv = 2, \ .xtal_accuracy = NRF_CLOCK_LFCLKSRC_XTAL_50_PPM} </code></pre><div style="clear:both;"></div>
