high current in System offhttps://devzone.nordicsemi.com/f/nordic-q-a/21188/high-current-in-system-offI don&#39;t understand why i have a current consumption of 0.535mA in system off. In my soft i use PWM, SPI a Button,, I put all things off before i go to system off but still not understanding why is high.. Any one have had such a problem with a consumptionen-USTelligent Community 13Wed, 19 Apr 2017 10:55:41 GMTRE: high current in System offhttps://devzone.nordicsemi.com/thread/82918?ContentTypeID=1Wed, 19 Apr 2017 10:55:41 GMT137ad170-7792-4731-bb38-c0d22fbe4515:5dd83d50-4181-4cb6-a971-e9e773c6264dToTo<p>To reply :</p> <p>The problem was because of a external pull up resistor..I took it of and everything is ok.

It is probably from the hardware, In fact I tested my Soft in another hardware I have and I have 0.3 μA in Sytem Off. I&#39;ll share whenever I find the exact reason...</p><div style="clear:both;"></div>RE: high current in System offhttps://devzone.nordicsemi.com/thread/82916?ContentTypeID=1Fri, 07 Apr 2017 08:45:06 GMT137ad170-7792-4731-bb38-c0d22fbe4515:86566385-d968-4e99-b793-43cba7801974Sigurd<p>Hi,</p> <p>Are you debugging when doing the measurements? In debug mode system off does not work. Instead, emulated system off is used which does not go to deep sleep and the CPU continues to run. System OFF will be emulated to secure that all required resources needed for debugging are available during System OFF. If you are not in debug mode, another theory could be that a GPIO interrupt is waking up the chip immediately after you enter SystemOff.</p><div style="clear:both;"></div>
