How can nRF51822-mKit make nRF51822 enter System OFF mode?

Hi

I'm trying to make nRF51822 enter System OFF mode, but I have not been able to find the way to do it yet. Could you show me the way with example code?

Best regards

sd_power_system_off() [declared in nrf_soc.h].

Accepted Answer

Thank you for your response, Rohit. Please let me ask you one more question. Is it impossible to make nRF51822 enter System OFF mode by using nRF51822 library? https://developer.mbed.org/teams/Nordic-Semiconductor/code/nRF51822/docs/tip/ Do I have to include "nrf_soc.h"?

I'm developing nRF51822 with LPC11U68 as mbed interface.

I believe the best you could do is to include "nRF5xGap.h" which will include "nrf_soc.h" internally.

I see. Thank you for quick reply!

an even easier way is:

NRF_POWER->SYSTEMOFF=1;
