Calibration can be turned off by adding&nbsp;CLOCK_CONTROL_NRF_K32SRC_RC_CALIBRATION=y to&nbsp;your prj.conf file.</p> <p>Also, you should remove the while loop you have in main() to allow the idle thread to run. The idle thread will call __WFE() to allow the chip to enter System ON (sleep).</p> <p>Best regards,</p> <p>Vidar</p><div style="clear:both;"></div>
