https://devzone.nordicsemi.com/f/nordic-q-a/73539/reduce-leds-consumption-thingy91---asset-trackerHi, I am trying to reduce the consumption of my Thingy91 device in idle mode. I am working with NCSv1.3 and the example asset_tracker. I am currently registering 0.60mA but if I disable the LEDs I get a 0.10mA idle consumption. I would like to been-USTelligent Community 13Fri, 09 Apr 2021 16:15:21 GMThttps://devzone.nordicsemi.com/thread/304079?ContentTypeID=1Fri, 09 Apr 2021 16:15:21 GMT137ad170-7792-4731-bb38-c0d22fbe4515:723b4590-c8a0-4fc5-90cc-1c8af519e6carqLST<p>Hi Carl,</p> <p>It was just what I was looking for. I have managed to reduce consumption by adjusting</p> <p>UI_LED_MAX<br />UI_LED_ON_PERIOD_NORMAL <br />UI_LED_OFF_PERIOD_NORMAL</p> <p>Thank you very much!!</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/303557?ContentTypeID=1Wed, 07 Apr 2021 14:24:00 GMT137ad170-7792-4731-bb38-c0d22fbe4515:eb67ec7f-f542-48b7-a80c-1ced29dd51e8Carl Richard<p>Hi!<br /><br />Thanks for reaching out! A good place to start would be to investigate how the LEDs are used by the asset_tracker, specifically the UI module and the led_pwm code. I suggest experimenting a bit with the defines in ui.h, for example by setting&nbsp;UI_LED_MAX to a lower value. You can also find the defines&nbsp;UI_LED_ON_PERIOD_NORMAL and&nbsp;UI_LED_OFF_PERIOD_NORMAL here, that can be used to limit how long the LEDs stay on/off. If you want even more control you can use the led_pwm code.<br /><br />I&#39;d also suggest moving to NCS version 1.4.x or 1.5.x if possible.<br /><br />Best regards,<br />Carl Richard</p><div style="clear:both;"></div>
