SYSTEM OFF

[Bluesky]

Hi, I would like to ask how can i get the current consumption that was stated in the datasheet which is 0.7uA  and the value I get from the reading is about 8-9 uA. 

#include "boards.h"

/**
* @brief Function for application main entry.
*/
int main(void)
{
NRF_POWER->SYSTEMOFF = 1;
}
/** @} */

Is this the right code as mention above?? Do I need to do any configuration in the other part of the FW or HW?

I am using the example code from : nRF5_SDK_14.2.0_17b948a\examples\peripheral\template_project

Thanks for helping!

Please add a loop after calling SYSTEMOFF

int main(void)
{
NRF_POWER->SYSTEMOFF = 1;

for(;;){__WFE();}
}

The chip consumes less than 1 uA in System OFF, so if you get 8-9uA there must be something wrong with your measurement setup.

When I add the for loop <for(;;){__WFE();}> I got a higher current draw compare with the code without the for loop. The current now is about 30uA.

This is not possible. Then it must be something wrong with your measurement setup.
