Hi,
I am working on the STM32WB55 with FreeRTOS and using the BLE stack on CPU2. Now, I need to implement STOP mode for the entire MCU. Ideally, I would like to put CPU1 into either RUN or STOP0 mode. I am used to handling this on simpler MCUs like the STM32L0xx. Is there anything specific I should be aware of with the STM32WB55?
I am working with CubeMX, and I noticed it generated files such as stm32_lpm.c and stm32_lpm_if.c. I assume these are meant to be used for my power management requirements.
If I call the function e_BLE_AppResult BLE_AppTurnOff(void), can I then put CPU1 to sleep in the same way as, for example, the STM32L0?
Thanks for your help!

Hello @JR2963
To understand how to implement a low power mode on an STM32WB running a FreeRTOS BLE application, I suggest you to Follow Chapters 4.6 and specially 4.9 of the AN5289. They should give you the necessary information.
Best Regards.
