WB55: Sleep current too high

[G5658]

I tried flashing PWR_STANDBY_RTC and PWR_EnterStandbyMode examples both has sleep current of 590uA. How do i get the datasheet value of 600nA standby current or atleast something less than 10uA.

Shouldn't current be measured at JP3 and not JP2?

[Peter BENSCH]

Well, JP3 and JP2 are connected in series, so either one would make the measurement of the current consumption possible.

JP3 relates to the VDD of the WB55, while JP2 also includes VDDSMPS.

It seems once flashing is done, i need to remove the jumper in JP5 that connects VDD to T_VDD or else the level shifter will burn 600uA+ of current.
