EEPROMs usually have limited write cycles and the datasheet for both Arduinos and the PIC18LF46K22 micros inside the RN2483 module lists 100,000 erase/write cycles.
This means if you’re sending 5 messages/hour every day and recording to EEPROM every time you’ll potentially kill the EEPROM in about 2 years.
Maybe not a huge concern, just something to keep in mind.
