Functional - Vega Absolute M-BUS-1 User Manual

Vega M-BUS-1 supports two activation methods in the LoRaWAN
OTAA. Select one of the methods via the "Vega LoRaWAN Configurator" application (see "User
Manual" on the program).
ABP method. After pressing the start button, the device immediately starts working in the
"Active" mode.
OTAA method. After pressing the start button, the device makes three attempts to
connect to the network within the set frequency plan. After the activation in the LoRaWAN
network is confirmed, the device sends a signal (LED flashing for 5 seconds) and switches to
the "Active" mode. If all attempts fail, the counter will continue to accumulate data and will
attempt to connect to the network every 6 hours.
Hold the start button pressed (min. 5 seconds) to switch the device from the "Active"
mode back to the "Storage" mode without turning off the power (battery or external).
The readings are collecting from the meter with a configurable period from 5 minutes to
24 hours. The readings stored in the device memory and transmitting during the next
communication session with the LoRaWAN
The readings are read from the connected device at 00.00 on the internal clock of the
device if the data collection period is set to 24 hours, at 00.00 and at 12.00, if the period is 12
hours and so on.
The adjustable data transfer period can be from 5 minutes to 24 hours. Data transferring
in random point in time during set 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 are remained 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. After communication session there are no non-transmitted messages in
the device memory.
The internal clock is set automatically when device connected to the "Vega LoRaWAN
Configurator" throughUSB, also can be adjust via LoRaWAN
