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

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.

3. Packet with time correction request.

Sent every seven days on LoRaWAN port 4
Size in bytes
1 byte
4 bytes
After receiving this type of package, the application can send to modem the packet with
time correction.
