ppk Current measurement problem

[jifu]

I set sd_app_evt_wait in vPortSuppressTicksAndSleep and got the average current. is 0.7ma, Using Other tool measurement, this demo will suddenly increase to a few dozen mA after running for a few seconds. I don't know what the problem is?
The code is as follows:
Thank you all

if ( xModifiableIdleTime > 0 )
{
#ifdef SOFTDEVICE_PRESENT
/* With SD there is no problem with possibility of interrupt lost.
* every interrupt is counted and the counter is processed inside
* sd_app_evt_wait function. */
portENABLE_INTERRUPTS();
sd_app_evt_wait();
#else
/* No SD - we would just block interrupts globally.
* BASEPRI cannot be used for that because it would prevent WFE from wake up.
*/
__disable_irq();
portENABLE_INTERRUPTS();
do{
__WFE();
} while (0 == (NVIC->ISPR[0] | NVIC->ISPR[1]));
__enable_irq();
#endif
}

This happened when I adjusted the voltage of PPK to 3.6V too!

Hi, the voltage slider on the PPK is not very stable, so I think it is better to leave it alone and set the power select switch to the DK position (Using the same voltage as the DK)

You say that the current increase to "a few dozen mA" after running for a few seconds. A few dozen is per definition more than 24mA. The nRF52832 chip can not consume 24mA or more.

The User Guide states, that if you measure an application running on a DK (acting as host for the PPK), then you should NOT use the regulator as supply.
