https://devzone.nordicsemi.com/f/nordic-q-a/125144/spikes-consumption-on-npm13004-with-no-loadHello, I am testing the power consumption of the npm1304 for the first time. To do this, I am using the PPK2 connected to the nPM1304-EK on VBAT and GND of the P1 connector. I have nothing connected to the Buck and LDO. I have disabled the FUEL Gaugeen-USTelligent Community 13Fri, 31 Oct 2025 09:42:12 GMThttps://devzone.nordicsemi.com/thread/552972?ContentTypeID=1Fri, 31 Oct 2025 09:42:12 GMT137ad170-7792-4731-bb38-c0d22fbe4515:2c0819c1-e3bd-4019-bd73-51efc006b215ketiljo<p>Just write &#39;help&#39; in the shell</p> <p><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1761903730004v1.png" alt=" " /></p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/552824?ContentTypeID=1Wed, 29 Oct 2025 21:30:54 GMT137ad170-7792-4731-bb38-c0d22fbe4515:ec62a731-0e00-4c71-a1dc-c4b6e4e9fafcEmmanuel JEZ<p>Thank you for these explanations.<br /><br />Could you send me a link where I can find the list of shell commands for the npm1304?&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/552225?ContentTypeID=1Thu, 23 Oct 2025 10:27:18 GMT137ad170-7792-4731-bb38-c0d22fbe4515:28f47049-80bc-4c70-8551-6a0c51e9bb84ketiljo<p>I assume the EK is used with the PowerUP app. The nPM Controller on the EK is instructed to sample measurements once a second which involves multiple I2C transactions - hence the current spikes. Disabling the Fuel Gauge in the GUI stops the measurement processing but not the sampling itself.</p> <p>As of now, there are no ways to disable this polling from the GUI... Two options here:</p> <ol> <li>Close PowerUP and power cycle the EK (nPM Controller USB port). As long as nPM Controller is not connected to the PowerUP, there will be no I2C transactions. Bucks can be disabled with the BUCK STARTUP CONFIG headers (ground to disable) - need a PMIC power cycle too</li> <li>Use shell manually to disable sampling (command&nbsp;<span><em><code>npm_adc sample 0</code></em>)</span></li> </ol> <p><span><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1761215143738v1.jpeg" alt=" " /></span></p> <p><span><img style="max-height:240px;max-width:320px;" src="https://devzone.nordicsemi.com/resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/pastedimage1761215156145v2.png" alt=" " /></span></p> <p><span></span></p><div style="clear:both;"></div>
