To restore the data from a backup file, the Access Password at the new transceiver must be set the same as the Access Password at the transceiver that was originally backed up.
Additionally, the new device must have uploaded correct files for the given network (DPA plug-in, TR configuration with correct Access Password, and possible Custom DPA Handler) before the restoring.
The Restore is implemented as a service (a group of DPA commands) available in IQRF IDE or IQRF GW Daemon.
