[826896167]

Current consumption
BLE event total charge	9.10 µC
Idle current	2.0 µA
Total average current	89 µA

I used nordic ble_app_pwr_profiling，nordic PCA10040，test instrument is N6705C，but my test is 6-7uA，why？

Hi,

Can you just do a simple:

int main(void)
{
  while(1)
  {
    __WFE();
  }
}

Also make sure you read:

Best regards,

Thanks you kenneth!

I used rtc app，modify flow code：

int main(void)
{

    while (true)
   {
       //__SEV();
       //__WFE();
       __WFE();
   }
}

the reset is：4-5 uA

And there's another problem,I'm not sure what makes the little spear??

thanks,Best regards.
