Data transmits via MQTT protocol. You should specify in the device settings the address
and port of the server where the data will be sent. Those settings specified in application “Vega
NB-IoT Configurator”. It must be MQTT broker as a server (received side). You should specify
in the device settings the address and port of the broker. Also, you should specify a topic name
where the data published and a client name – the name which the device use for publishing.
All those settings specified in “Vega NB-IoT Configurator” in part “MQTT settings”. For watching
