NRF52832 DK --PCA10040 current measurement

[Astor]

Hi,

I'm evaluating BLE power consumption with a PCA10040 nRF52DK and a PPK, I cut SB9 and did nothing else with DK.

No peripheral is used in projects, Buttons or LEDs, but I got 18uA idle current after 1minute. Before which idle current is above 200uA, but anyway it exceeded the value written on specification.

Could I have any suggestion how to measure the current with nRF52DK and PPK?

Also I will use an Agilent 66319 power analyzer for formal measurement, but nothing was mentioned in nRF52 handbook. Please also help on it, thanks a lot.

BTW, I'm modifying ble_app_blinky project with comment out button_init and led_init.

Set DCDC enable and adv TX power to 0dBm
