How to configure the use of power management APIs and Kconfig in nRF Connect SDK v3.1.1 or other versions.

[Scott Li]

Hello Nordic Support Team,
  I am developing BLE content, where nodes will be periodically uploaded to the gateway.During this interval,the CPU needs to be kept idle, waiting to be awakened for the next data upload.

But I didn't find anything related to this in the SDK's sample project.
  I only know that nRF5_SDK has a idle_state_handle function that goes to system_on idle mode and system_off sleep mode.

Thank you in advance for your support!

Hi!

With Zephyr this is handled by the idle thread if you have enabled power management in the Kconfig(config_pm=y). If nothing is happening then the idle thread will put your device into sleep.
