@Arjun765
By calling HAL_RTC_SetAlarm_IT you're bypassing mbed Time layer so this is not recommended to do so. You should rather use mbed APIs.

mbed is designed so that you can program any timer and mbed-os is in charge of programing RTC or low power tickers to wake-up the system when needed, you don't have to program an RTC alarm explicitly.

There have been many similar discussions for instance here : #7156

@Arjun765 We're going to close this as a non-issue based on the comments from @LMESTM. If you have a problem using the Mbed API please raise a new issue.
