sleep mode of nRF52840 in NCS

[peter_liu]

I'm working on NCS 1.6.1 for both nRF52840 and nRF9160.

I'm trying to put my devices into sleep mode so i reviewed some related tickets and found following ways.

NRF_REGULATORS->SYSTEMOFF=1     //this seems only to be supported in nrf9160

and

pm_power_state_force(struck pm_state_info info)

i wonder what is the better way to go with? and what is the difference between these two? 

and are there any samples showing how to  manipulate sleep mode?

Hi

Please check out the nRF5x system OFF sample project in Zephyr which uses pm_power_state_force correctly to force an nRF5x device to system OFF. It can be found in ...\<NCS_FOLDER>\v1.7.0\zephyr\samples\boards\nrf\system_off\src\main.c

Best regards,

Simon
