exit STANDBY every second from RTC on STM32F100RBT

Hello,

I'm using STM32F100RBT. How can I use HAL_RTCEx_SetSecond_IT to exit STANDBY mode?

I'm able to exit STANDBY using ALARM, and able to get an interrupt every second using HAL_RTCEx_SetSecond_IT , but I can't wake up from standby with it.

What should I do?

Is there an example project?

Thanks!
