Hi Team,

I’m using STM32WLE5 MUC for Lora communication (SubGHz_Phy), I want to know is there a way to use Systick instead of timer ?
This is because I used RTC to some other use case. kindly share me the way for the same.

Info++:
if RTC settings is free running binary mode, Lora TX and RX is working, but if it is changed to free running BCD calendar and binary mode, the callback for HAL_RTC_AlarmAEventCallback function is not triggered for Alarm A.

Thanks,
