https://devzone.nordicsemi.com/f/nordic-q-a/26437/power-profilerI am using nRF52840 and the power profiler. I am trying to measure the current to evaluate the scheduling of BLE. Now I am using the ble_uart_c example and I changed the scan_interval to 0x0100 and the scan_window to 0x0050. I hope to see a half-halfen-USTelligent Community 13Tue, 31 Oct 2017 08:12:25 GMThttps://devzone.nordicsemi.com/thread/104026?ContentTypeID=1Tue, 31 Oct 2017 08:12:25 GMT137ad170-7792-4731-bb38-c0d22fbe4515:45fa082f-a049-41c4-870b-a318e1286b46Bj&#248;rn Kvaale<p>You need to cut SB40 on the board to get accurate current measurements. I did it by using a scalpel (or a sharp thin knife) and a microscope (or magnifying glass). You might not need the microscope if you can see very accurately, but it makes it a lot easier with a microscope. You want to cut enough metal so that SB40 is not shorted anymore (<a href="http://infocenter.nordicsemi.com/topic/com.nordic.infocenter.nrf52/dita/nrf52/development/nrf52840_pdk/prepare_board.html?cp=2_0_3_5_8_0">see link</a>). Also remember that the next time you want to flash an application on your nrf52 board, it is easiest to apply a jumper cable (or a <a href="https://www.digikey.com/products/en/connectors-interconnects/shunts-jumpers/304">shunt jumper</a>) on P22 like it says in the link.</p><div style="clear:both;"></div>
