the current consumption of the STM32WB55 in stop2 mode is about 116uA whici is much higher than it should be in the datasheet about 2uA.

I test it on P-NUCLEO-WB55 kit board which without any other devices connected on it with the official examples "PWR_STOP2_RTC" ,and I did test it as the readme.txt file tell me（remove all jumpers on JP5, and test the current on the JP2）, but the result is near 116uA.

Also I have test the standby mode with the "PWR_STANDBY_RTC" examples, the result is about 0.2uA which is ok.

So what's the matter would it be with the STOP2 mode about the big current?

Looking forward to your ​reply.

Thanks.

Hello , Is there anyone can give any suggestion please?

[Piranha]

Set DBGMCU_CR to zero before entering low-power mode.

Hi Piranha:

I've tried that, but it doesn't work.

Thanks.
