Packet With Data From Connected M-Bus Device In Universal Poll Mode; Packet With Time Correction Request - Vega Absolute M-BUS-2 User Manual

A package of this type is transmitted separately for each connected meter. For example,
if 5 metering devices are connected to the converter, 5 packets will be transferred to the next
connection.

array Data
LoRa data transmission technology imposes restrictions on the maximum packet size,
depending on the speed at which the given packet is transmitted. If the data received through
the external interface cannot be transmitted in one packet, they are split into several packets,
which are transmitted sequentially.
