Hello!
Is any body aware about how to wakeup a STM32 series MCU from sleep over I2C? 
So far I was aware of wake-up over GPI/Brown out Reset etc, but wake up over I2C?? Is this really possible? Please let me know if anyone has prior experience at this. Have a great day!

    Hello @abjames and welcome to the ST Community.

    I’ve seen the example of the STM32H563. It Even has the wake up capability from stop mode in a few cases using interrupteur. You may have a look at this example: I2C_WakeUpFromStop So, Check the PWR chapter of your MCU on the reference manuel. The. Have a look on the peripheral chapter. That should help you to discover the wake up capability.

    Best Regards.
