Hello @Nimit Vachhani

Yes, the RTC is used for precise timing in LoRa Sub-GHz PHY communication; 

The RTC provides a time base that operates in all power modes, ensuring uninterrupted timing services, and it's critical for maintaining synchronization and efficient power management during communication processes.
