It is difficult to implement IoT gateway solutions

• Tie together hardware and network resources • Different standards and legacy systems • Manage connectivity and network issues • Device management • Autonomous operation • Integrate data with existing enterprise systems and databases

App App

Kura is a Java/OSGi-based container for remote management and control

MQTT is a lightweight messaging protocol based on the publish/subscribe model. PAHO provides the MQTT client implementation.

CoAP (constrained application protocol) is a RESTful protocol, like HTTP over UDP. Californium implements the CoAP standard in Java

The Raspberry Pi Eclipse IoT Car

Use a remote console to move the car around in different directions

Publish pictures to an MQTT server for remote viewing

Configure the proximity limit at runtime

This is the top level of the application

13

Inside the MQTT interface block. It is

composed of 5 blocks from the library of

block

14

The CoAP interface block interacts wih the front-end application

via CoAP server

15

Server Client

The front end application used to vie and interact with the

data was also implemented with

Reactive Blocks. We used Java Swing.

16

Inside the CoAP interface block which

is composed of 6 block from the library of

17

18

The motor control is composed of 4 blocks

from the library of blocks

19

20

proximity limit

The proximity detector is composed of 3

blocks from the library of blocks

21

Config listener: Listens to changes in the configuration property Proximity limit. At runtime this property can be seen and set via the Kura´s web-console
