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

18
The motor control is composed of 4 blocks
from the library of blocks
19

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
