I'm looking for assistance or example sources of being able to dynamically control the Nordice device subsystems power. i.e. the serial uart used for the Zephry shell. But also how to dynamically get the Nordic into lower power states.

Hi,
Please take a look at this example https://github.com/nrfconnect/sdk-zephyr/tree/main/samples/boards/nrf/system_off

Is there an example with BLE being active on the network processor?
I'm sorry. But I don't see which sample has BLE connected or advertising. But still running at a very low power.
Hi,
Sorry. I have fixed the link directing to the correct part of nRF5340 Bluetooth Low Energy. Please check again.

What is the average power draw from that example on the DK?
I'm seeing 2.4 ma.
Hi,
The examples in NCS are not optimized for power. You can take a look at Power optimization and this blog for Optimizing Power on nRF5340 SoC Designs.

I'm still looking for my 2.5 ma of power.
And I'm going to push for an answer of something that is connected over BLE (even at slow data rates), but gets the power down much lower than 2.5 ma.

Hi,
Sorry, I am confused. What is your expectation for the average power? 2.5 ma or lower than 2.5 ma?
-Amanda
Much lower than 2.5ma. 0.25ma would be nice.
I know my board design can do down to 0.07 ma, but that's with BLE and the network processor turned off.
Hi,
You can refer to this blog for Optimizing Power on nRF5340 SoC to modify samples or try the example in that blog.
