We will inquire about current consumption when System On.

[psj]

I am currently using a 51dk board.
I am trying to study low power system_on_wakeup_on_gpio in github. I built this code and measured the amount of current. I would like to know why it consumes too much current compared to the expected current consumption.
github.com/.../nrf51-powerdown-examples This is my code.

Hi,

 

What is the current consumption that you are seeing? If it is around 1.2 mA, it indicates that the nRF51 device is in debug mode. Try power-cycling the chip, then measuring the current consumption again.

Cheers,

Håkon

I'm sorry for replying too late.
When the dk board enters low power mode, which is measured by average 0.5 mA.
