- UUID(Universally Unique Identifier): The UUID contains 32 hexadecimal digits, split into 5 groups.
- Major: This is a 2 byte string used to identify a smaller subset of beacons within a larger group
- Minor: This is a 2 byte string that identifies individual beacons.
- Tx Power: This is used to determine the proximity in which the beacon can broadcast.
