Intermittent failure when entering Standby Mode

Hello,

I'm encountering an issue while testing the Standby Mode on my device.

Most of the time, the device enters and wakes from Standby Mode successfully. However, after repeated testing, it occasionally fails to enter the mode.

What could be the potential causes for this failure?

Any suggestions on how to approach debugging this would be greatly appreciated.

Thanks.

Ensure that the conditions for entering standby mode are established.

    Hi @biopunk101 ,

    It depends on what you implement in the function "WakeUp_Enable()": Ensure that you clear any wakeup flag before enabling the wakeup source.
