Hey,
I tried to measure my setup as above in the title, to get the current consumption while using the nrf5340 according to this link:
High power consumption when running the BLE stack.
I do measure the consumption during BLE Advertising. However, I still seem to get a high consumption, as I would expect to get around 4 mA peaks according to the online power profiler (I use the PPK2 in Source Meter Mode with 3V as power, the Ampere_meter mode gives around the same values)
This is my PRJ.conf:

and this my hci_ipc:

And these are the values I get:
What am I doing wrong? I expect to get this:
