https://devzone.nordicsemi.com/f/nordic-q-a/53224/sdk-15-3-and-the-blox-nina-b3-starting-developmentHello everbody, I readed alot about the nrf52480 &quot;how to flash softdevice and the other stuff&quot;, but i cannot get the ble_app_gls working out of the scratch. I have the Arduino Nano 33 BLE which it has the blox nina-b3 with integrated nrf52480, i soldereden-USTelligent Community 13Wed, 16 Oct 2019 09:03:27 GMThttps://devzone.nordicsemi.com/thread/215232?ContentTypeID=1Wed, 16 Oct 2019 09:03:27 GMT137ad170-7792-4731-bb38-c0d22fbe4515:372e5046-6136-4549-977a-77a932076a7cAndreasF<p>Hi.</p> <p>Please try this:</p> <p><pre class="ui-code" data-mode="text">// &lt;h&gt; Clock - SoftDevice clock configuration //========================================================== // &lt;o&gt; NRF_SDH_CLOCK_LF_SRC - SoftDevice clock source. // &lt;0=&gt; NRF_CLOCK_LF_SRC_RC // &lt;1=&gt; NRF_CLOCK_LF_SRC_XTAL // &lt;2=&gt; NRF_CLOCK_LF_SRC_SYNTH #ifndef NRF_SDH_CLOCK_LF_SRC #define NRF_SDH_CLOCK_LF_SRC 0 #endif // &lt;o&gt; NRF_SDH_CLOCK_LF_RC_CTIV - SoftDevice calibration timer interval. #ifndef NRF_SDH_CLOCK_LF_RC_CTIV #define NRF_SDH_CLOCK_LF_RC_CTIV 16 #endif // &lt;o&gt; NRF_SDH_CLOCK_LF_RC_TEMP_CTIV - SoftDevice calibration timer interval under constant temperature. // &lt;i&gt; How often (in number of calibration intervals) the RC oscillator shall be calibrated // &lt;i&gt; if the temperature has not changed. #ifndef NRF_SDH_CLOCK_LF_RC_TEMP_CTIV #define NRF_SDH_CLOCK_LF_RC_TEMP_CTIV 2 #endif // &lt;o&gt; NRF_SDH_CLOCK_LF_ACCURACY - External clock accuracy used in the LL to compute timing. // &lt;0=&gt; NRF_CLOCK_LF_ACCURACY_250_PPM // &lt;1=&gt; NRF_CLOCK_LF_ACCURACY_500_PPM // &lt;2=&gt; NRF_CLOCK_LF_ACCURACY_150_PPM // &lt;3=&gt; NRF_CLOCK_LF_ACCURACY_100_PPM // &lt;4=&gt; NRF_CLOCK_LF_ACCURACY_75_PPM // &lt;5=&gt; NRF_CLOCK_LF_ACCURACY_50_PPM // &lt;6=&gt; NRF_CLOCK_LF_ACCURACY_30_PPM // &lt;7=&gt; NRF_CLOCK_LF_ACCURACY_20_PPM // &lt;8=&gt; NRF_CLOCK_LF_ACCURACY_10_PPM // &lt;9=&gt; NRF_CLOCK_LF_ACCURACY_5_PPM // &lt;10=&gt; NRF_CLOCK_LF_ACCURACY_2_PPM // &lt;11=&gt; NRF_CLOCK_LF_ACCURACY_1_PPM #ifndef NRF_SDH_CLOCK_LF_ACCURACY #define NRF_SDH_CLOCK_LF_ACCURACY 1 #endif // &lt;/h&gt; </pre></p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/215159?ContentTypeID=1Tue, 15 Oct 2019 19:05:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a1432808-3fe2-4ddc-b07d-45ec409b416fgianmarcov<p>Hi Andreas,</p> <p>In the sdkconfig.h i&nbsp;tried with</p> <p>NRF_SDH_CLOCK_LF_SRC,&nbsp;CLOCK_CONFIG_LF_SRC,&nbsp;NRFX_CLOCK_CONFIG_LF_SRC to 0 and i tried the default 1.</p> <p>I set the&nbsp;NRF_SDH_CLOCK_LF_ACCURACY to 1 because i hed an error on compilation time.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/215042?ContentTypeID=1Tue, 15 Oct 2019 11:21:02 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a4f94625-9742-4374-b111-2bfb52d41019AndreasF<p>Hi.</p> <p>Which clock configuration are you using?</p> <p>Best regards,</p> <p>Andreas</p><div style="clear:both;"></div>
