In my application I need to switch periodically between run mode and very low power stop mode. I use the RTC alarm interrupt to exit the stop mode  which works just fine. However, after exiting the stop mode the serial communication stops working. Do I need to deinit the uart before entering the stop mode and initializes it again after exiting? hope someone can help me? thanks
