nRF5340 power management mechanism to wake up Application core from connected network core received data.

[MichaelSe]

Hi Nordic FAE, Merry Christmas:

We are using nRF5340 with nRF Connect SDK V2.6.1 running on Zephyr OS.

Do you have the nRF5340 power management guideline document?

Function definition:

Case 1. Both Application core and Network core are power off - sys_poweroff();

What API can I configure the Application core wake up sources?

Case 2. Application idle but Network core still kepp connected.

What API can I configure the Application core below wake up source (WFI/WFE)?

a. While connected status Network core receives Gatt profile, there shall has a mechanism to wake up Application core.

b. While Key pressed event happen, there shall has a mechanism to wake up Application core also.

Hi,

Do you have the nRF5340 power management guideline document?

Case 1. Both Application core and Network core are power off - sys_poweroff();

Wakeup capability.

Case 2. Application idle but Network core still kepp connected.

What API can I configure the Application core below wake up source (WFI/WFE)?

The nRF5340 already is configured to be sleeping whenever possible.

Are you asking because you see too large current consumption numbers already and want to reduce them?

How much does it use for you now?
