Abstract

Cilj ovog rada bio je, korištenjem programskog alata Eclipse Kure na uređaju Raspberry Pi, prikupljanje podataka sa senzorskih čvorova korištenjem različitih komunikacijskih tehnologija (XBee, Bluetooth Low Energy, LoRaWAN, WiFi) koje su u sklopu rada i ukratko predstavljene. Nakon dohvaćanja podataka sa senzorskog čvora, podatci su obrađeni i poslani na poslužitelj MQTT protokolom. U radu je opisan rad sa formatom poruka KuraPayload te način kako izbjeći korištenje tog formata radi čitljivosti dolaznih poruka sa poslužitelja.

Komunikacija preko XBee modula je u potpunosti ostvarena dok su se pojavili određeni problemi prilikom korištenja Eclipse Kure prilikom razvoja servisa za serijsko čitanje (korišten za WiFi i LoRaWAN modul) te problemi sa uređajem Raspberry Pi prilikom osposobljivanja za komunikaciju putem modula Bluetooth Low Energy.
Svi uočeni problemi te razvoj servisa za svaku tehnologiju su opisani u radu.

Abstract (english)

The aim of this paper was to use the Eclipse Kure software tool on Raspberry Pi to collect data from sensor nodes using different communication technologies (XBee, Bluetooth Low Energy, LoRaWAN, WiFi) that were briefly presented within the paper.
After retrieving data from the sensor node, the data was processed and sent by MQTT protocol to the server. This paper describes how to work with the KuraPayload message format and how to avoid using this format for readability of incoming messages from the server.

Communication via the XBee module has been fully realized while some problems have emerged when using Eclipse Kure when developing serial reading services (used for WiFi and LoRaWAN modules) and problems with the Raspberry Pi device when communicating via the Bluetooth Low Energy module.
All identified problems and service development for each technology are described in the paper.
