https://test-devzone.nordicsemi.com/f/nordic-q-a/87771/current-measurement-on-nrf9160Hello. I am doing current measurements on nrf9160dk while sending ~1kb json file through mqtt. I am following this guide: https://infocenter.nordicsemi.com/topic/ug_nrf91_dk/UG/nrf91_DK/hw_measure_current.html .

You can use the <a href="https://test-devzone.nordicsemi.com/power/w/opp/3/online-power-profiler-for-lte">nRF91 Online Power Profiler</a> to get an estimate of the current you should see if you play around a bit with the configurations on the left hand side to suit what your application does. If your actual current measurements differ a lot from those, that points to something being set up in either your measurement setup or in your application.</p> <p>Best regards,</p> <p>Simon</p><div style="clear:both;"></div>
