https://devzone.nordicsemi.com/f/nordic-q-a/87628/nrf52832-current-consumption-problemHi I have been doing some current consumption measurements using Nordic&#39;s Power Profile Kit 2. The device I am measuring is a custom BLE device that uses the ADC to sample @ 256Hz, reads data from an accelerometer (MC3672) when the data ready pinen-USTelligent Community 13Fri, 06 May 2022 10:40:05 GMThttps://devzone.nordicsemi.com/thread/366679?ContentTypeID=1Fri, 06 May 2022 10:40:05 GMT137ad170-7792-4731-bb38-c0d22fbe4515:b649ffd1-30c4-499b-94b8-83465c1f2f8dEdvin<p>Hello,</p> <p>It is not clear to me at this point in time what causes these bumps occcuring every 60ms (ish?).</p> <p>If your three main suspects are the ADC, radio or SPI, I suggest you try to disable one at the time, and see whether the bumps disappear.&nbsp;</p> <p>You aren&#39;t using any LEDs or something in your application at approximately every 60ms?</p> <p>Are you running this on an nRF52832 DK, or do you have some other custom HW? Are you measuring only the current on the nRF52832 chip, or are the external chips being powered from the nRF as well?</p> <p></p> <p>Best regards,</p> <p>Edvin</p><div style="clear:both;"></div>
