I am trying to set alarm canitnously in loop every 4min.

But it is working only 5 time.
Is there any way to set alarm cantinously after every 4 min.

Hello @Kai_Satone ,

Are you using alarm masks to make infinite periodic?

I recommend you to take a look at this wiki Getting started with RTC - stm32mcu. This wiki explains how make infinite periodic using alarm masks.

I hope this help you!
