https://devzone.nordicsemi.com/f/nordic-q-a/67953/sleep-current-while-advertisingWith 900ms advertising interval we are seeing ~50uA sleep current on the 52840. How do we make it sleep with lower current? We are using an example project with an idle_state_handle call in the main, which calls nrf_pwr_mgmt_run, and executes a WFE.

Please make sure that if you have any other peripherals enabled, try disabling these before calling the idle_state_handle() function. It won&#39;t be efficient to go into system OFF mode, so I would think one of the<strong> ION_RAMON_</strong>&nbsp;scenarios would be your best bet.</p> <p>You can also check out <a href="https://devzone.nordicsemi.com/nordic/short-range-guides/b/hardware-and-layout/posts/nrf51-current-consumption-guide">this current consumption guide for nRF51</a> (which is still relevant for the nRF52 series) for a lot of common ways to reduce/optimize current consumption.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
