Over current 500ua in system on mode

Hi
Yes. I use a custom board.
Are you saying you need a source file? The current test removed all sensors. The PCB only has nrf52832. At present, about 470uA is generated even if you do the following.

The sdk_config.h file is attached.
Please confirm.

Hello,

Is this your custom board? could you please share the code snippet of system on mode where the nRF power management function is called?

I used ble_app_uart.
Current measurement was done with a multimeter.
Seeing that it comes out as 1~2uA in system off mode, I think it is accurate considering the error.

I also know the current that must occur in system on mode.
In system on mode, I just want to know if I need to control it in a different way.

Hello,

This is the current consumption on sleep mode.

Which example you are working on and how have you measured the current?

Thanks.
