stm32wb5mmg CPU2 do not go to sleep

[Vandr.1]

Hello,
I have an STM32WB5MMG chip, and I work with power consumption. I have the problem that after I stop advertising (aci_gap_set_non_discoverable()), I see that a flag LL_PWR_IsActiveFlag_C2DS() is still False, and I can not switch to Switch_On_HSI(). Why does the CPU2, after stopping advertising, not go to deep sleep mode?

Hello,

can you please share more details? Can you show any measurement or code?

Also, would it be possible to share the project?

Thank you.

Best regards,
