The data transfer period can be adjusted from 5 minutes 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 on, the device will send the next packet only
after receiving a confirmation of the delivery of the previous one. If such confirmation has not
received after the fulfilled in the settings uplink number of transmissions, device completes the
communication session until the next one according to the schedule. In this case, the device
continues to collect data according to the data collection period and store it in memory. Non-
transmitted packets remain in the device memory until the next communication session.
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.
