Hello All,
I am getting these ~3.5mA current spikes very 4 seconds and I can't seem to figure what the cause of them is. some of the spikes have a single spike/pulse while other have multiple. please see the attached images. I have commented out everything except the while in the main function and no difference. I have also commented out the enabling of the DCDC and still the same issue. any help would be greatly appreciate. I have a feeling its in the project config setting but tried commenting out what I thought may be the cause but no change either.
I am using a custom board with 52833 and nRF Connect SDK 2.0.0. the board does have other ICs(hall sensors) but I measured their consumption and had no spikes.
while (1) {
//k_sleep(K_SECONDS(1));
//k_msleep(500);
__WFE();
}
