,
Issue was deeply investigated by our expert.
Root cause seems to be related to the factwhen 2 RTC alarms occur one just after the other, the first alarm is hiding the second one.
The suggested workaround is to replace current implementation ofHW_RTC_IrqHandler in HW_RTC.c file by the following one:
void HW_RTC_IrqHandler ( void ){ RTC_HandleTypeDef* hrtc=&RtcHandle; /* enable low power at irq*/ LowPower_Enable( e_LOW_POWER_RTC ); /* Get the AlarmA interrupt source enable status */ if(__HAL_RTC_ALARM_GET_IT_SOURCE(hrtc, RTC_IT_ALRA) != RESET) { /* Get the pending status of the AlarmA Interrupt */ if(__HAL_RTC_ALARM_GET_FLAG(hrtc, RTC_FLAG_ALRAF) != RESET) { /* Clear the AlarmA interrupt pending bit */ __HAL_RTC_ALARM_CLEAR_FLAG(hrtc, RTC_FLAG_ALRAF); /* Clear the EXTI's line Flag for RTC Alarm */ __HAL_RTC_ALARM_EXTI_CLEAR_FLAG(); /* AlarmA callback */ HAL_RTC_AlarmAEventCallback(hrtc); } }}�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?�?
This fix will be available in coming release of I-Cube-Lrwan package.
