[RK25] What is the Session for in EZConfig?
Last Updated 2 years ago
UHF RFID EPC GEN 2 standard has 4 sessions for inventory; session 0 ~ 3. These sessions two purposes:
1. Determines when a tag will respond to a query from the reader
2. Allows tags to maintain independent states when communicating with multiple readers at the same
time.
When the RFID reader inventories a tag, the session flag state is changed from 'A' to 'B' - how long the tag stays in the 'B' state before reverting back to the 'A' state is called "persistence".Exactly persistence time cannot set but it will be effected because of search mode and session.
