https://devzone.nordicsemi.com/f/nordic-q-a/56077/minimizing-power-consumption-in-system-onHello, I am trying to use as least energy as possible. I run the ble_app_blinky example. The only change I did was commenting out: advertising_start(); such that no advertising will take place. In the main loop of this example, there is a call to idle_state_handleen-USTelligent Community 13Thu, 02 Jan 2020 16:51:05 GMThttps://devzone.nordicsemi.com/thread/227302?ContentTypeID=1Thu, 02 Jan 2020 16:51:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:6b911807-332f-487a-9656-33077991ff84matan<p>1. How can I turn RAM retention off?</p> <p>2. Can I avoid the slow clock to save energy?</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/227301?ContentTypeID=1Thu, 02 Jan 2020 16:46:33 GMT137ad170-7792-4731-bb38-c0d22fbe4515:dd4e46cd-84d0-4cdd-826d-f569e1c4f5d0Vidar Berg<p>Hello,</p> <p>RAM retention is enabled by default and the Softdevice will start the slow clock (32Khz) during initialization so expected sleep current should be closer to <span>I</span>ON_RAMON_RTC in your case. But that&#39;s if you have disabled debug logging in sdk_config.h as well. Please make sure&nbsp;NRF_LOG_ENABLED is defined as &#39;0&#39;.&nbsp;</p><div style="clear:both;"></div>
