Hi all , hi NORDIC team , I'm currently developping a multiprotocol adapter LORA/BLE . I'm using the sd130 . Semtech's third party says that it's "recommended " to have an RTC for developping the software. In fact i need to keep track of the TIME AND CALENDAR . After looking in the forum . I've found that i could implement a Software RTC using nrf51422 real time counter "RTC" which is not accurate enough . In the other hand , I'm thinking of a hardware solution which consists of an external RTC .
