How to power off a device in the Nordic, under application control. In a Zephyr environment?

[Jordan Archer]

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?

Hi, 

See the Bluetooth Low Energy doc for nRF5340.

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.
