session. The data transfer period can be adjusted from 1 to 24 hours. Data transfer is carried out
by a random time at the selected period. At the next communication session, the device starts
sending accumulated packets with readings, from the earliest to the latest.

With the "Confirmed uplinks" option turned off, the device just sends all accumulated
packets to the network in order from the earliest to the latest. There are no checks of package
delivery in this mode. There are no non-transmitted messages in the device memory.
