That is a typo, should be "NRF_POWER->SYSTEMOFF = 1;"

Hi Jorgen,

our device is not using SoftDevice, therefore I conclude I need to use NRF_POWER->POWEROFF = 1;

Which header file do I need to include in order to get pass the compile error: "'NRF_POWER_Type' has no member named 'POWEROFF'"?

Thanks,

Simon

Updated. It looks like the old link linked to the correct page, just not to the section about System OFF mode.

Ho Jorgen,

Could you please refresh system mode off Link in you reply. With Nordic semi's switch to new infocentre location,most of the links in the forum are broken.

Thanks and regards,

Hi,

The end result of sd_power_system_off() and NRF_POWER->POWEROFF = 1 is the same. When the softdevice is initialized, you should use sd_power_system_off(), which make sure the softdevice is not in the middle of a critical operation when putting the device into system off mode.

Without the softdevice, sd_power_system_off() is not available, and it is safe to use NRF_POWER->POWEROFF = 1.

Notice that the device is not OFF when you put it in system off mode, it is put in a low power/deep sleep state, where it can only be waked up by reset, GPIO, NFC field or LPCOMP module.

Best regards,

Jørgen
