Is RTC needed on STM32WLE5Cx

[Nimit Vachhani]

Greetings,

This is my frist time with wireless mcu. I just want to ask whether RTC is required for LORA Sub GHz Phy communication ? 

Any help will be greatful.

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.
