This can be done by setting the define&nbsp;<strong>NRF_LOG_BACKEND_RTT_ENABLED to 0</strong> in your project&#39;s sdk_config.h file. You can also disable logging entirely to minimize current consumption if that&#39;s of interest by setting the NRF_LOG_ENABLED define to 0.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
