How to put NET core into and out from SLEEP (or DEEP-SLEEP) mode in nRF530 Chip from APP core?

We need this to save power consumption and if possible shutdown the NET core completely when BLE communication is not required. Is there a way to control the power modes of the NET core from the APP core without restarting the nRF530 chip?

Hi,

You cannot put just the network core in system OFF mode while using the app core, so the lowest power mode you can use in this case, is system ON low power mode (CPU sleeping while waiting for event). This is also the default behavior in the nRF Connect SDK, where the idle thread will enter system off mode.
