the "Active" mode. If all attempts fail, the device 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 device forms the data packet with current state with a configurable period from 5
minutes to 24 hours. The packets stored in the device memory and transmitting during the
next communication session with the LoRaWAN
Examples
If the data collection period is set to 24 hours the packet is formed at 00.00 on 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.
Data collection period when measurements are out of specified current value range set
independently and may be equal from 5 minutes to 24 hours.
The adjustable data transfer period can be from 5 minutes to 24 hours. When
beginning of communication session, the device starts sending packets with readings from
the earliest packet. The time of data transmitting cannot be specified, it's defined in random
way for every device in chosen period of transmission from the moment of connection to the
network.
Example
Transmission period is 30 minutes, and device was started at 16:40 by the internal
device clock. In random way the device calculate data transmitting time and set it at 16:41 in
the half-hour period from 16:40 to 17:10. Thus, packets from this device will transmit at 16:41,
at 17:11, at 17:41, at 18:11 and so on every 30 minutes by the internal device clock.
When measurements are out of specified current value range the communication
period still the same if parameter "Immediately send data when current is out of range" is not
active.
If that parameter is active and external power supplying, then the alarm message will
be forming and sending during 2 minutes after the moment of current value measurements
are out of specified range. If external power not supplying, then the converter will detect
exceeding the specified limits during the following data collection session according to the
schedule only, but the modem will send that data immediately too. Every following message,
which will form according to the data collection period, also will have sent immediately until
the current value measurements are back in range.
Current value range set in the "Vega LoRaWAN Configurator" application with
parameters "Current low threshold" and "Current high threshold". Current threshold set in mA
multiplied by 100.
