M-BUS-2 / User Manual
Vega M-BUS-2 device supports two activation methods in the LoRaWAN
and OTAA. One of the methods can be chosen using the «Vega LoRaWAN Configurator»
application (see the "User Manual" for the program).
Method ABP. After pressing the start button, the device immediately starts working in the
«Active» mode.
Method OTAA. After pressing the start button, the device will make three attempts to
connect to the network in the frequency plan specified when setting up. Upon receipt of
confirmation of activation in the LoRaWAN
indicator (glow for 5 seconds) and go into the «Active» mode. If all attempts are unsuccessful,
the counter will continue to accumulate data and will try to connect to the network every 6
hours.
It is possible to transfer the device from the "Active" mode back to the "Storage" mode
without disconnecting the power supply (battery or external) by long pressing the start button
(more than 5 seconds).
The device generates a packet with the current state with a configurable period from 5
minutes to 24 hours. Packets are saved in the device memory and are transmitted during the
next session of communication with the LoRaWAN
Example
If the data collection period is 24 hours, then the package will be generated at 00.00
according to the internal clock of the device.
If the data collection period is 12 hours, then at 00.00 and at 12.00, and so on.
The data transfer period can be adjusted from 5 minutes to 24 hours. When
communicating, the device starts sending packets with readings, starting with the earliest one.
The specific data transfer time cannot be set, it is determined randomly for each device within
the selected data transfer period from the moment of connecting to the network.
Example
The data transfer period is set to 30 minutes, and the device was started at 16:40
according to the device's internal clock. At random counting, the device was assigned the time
16:41 to transmit a packet in a half-hour period from 16:40 to 17:10. Thus, packets from this
device will be transmitted at 16:41, 17:11, 17:41, 18:11, and so on every 30 minutes according to
the internal clock of the device..
The internal clock is set automatically when connected to the device via USB, and can
also be adjusted via the LoRaWAN
