https://devzone.nordicsemi.com/f/nordic-q-a/86929/need-help-regarding-current-consumption-in-lpnHi, Mesh SDK: v5 Using nRF 528232 I had implemented the Low Power Node example from the SDK and found that the current it consumed using a 1000mAh 3.7V battery was around 450uA in low power mode and when polling it is around 560uA.

The LPN code was unmodified, but I was still getting the current higher than usual. The current after the LDR and PIR was removed was around 28uA. I will test the LPN with the devkit and will let you know the current.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/363225?ContentTypeID=1Wed, 13 Apr 2022 14:54:44 GMT137ad170-7792-4731-bb38-c0d22fbe4515:e040180b-5fe7-4b0f-b8b1-ca71451c2835Mttrinh<p>Hi,</p> <p>The current consumption seems a bit high. You should get a lower consumption after you establish a friendship with a friend node, the node will then be running in low power node.</p> <p>Are you using a custom application or our LPN example unmodified?</p> <p>Are you using a DK or a custom board?</p><div style="clear:both;"></div>
