layers
The levels of IrMC implementations refer to capabilities that are supported.
- Level 1
- is little more than a simple object push
- Level 2
- allows the transfer of a complete database (contacts, calendar) in one step (intended for backup / restore)
- Level 3
- access to individual entries in the databases (not very widespread)
- Level 4
- allows a synchronization, whereby only the entries are transmitted that have changed since the last synchronization
- Level 5
- should no longer OBEX , but on SyncML based
