Java and IoT
What we like about Java! Why Java?
6
Same language in many environments
Same language from device to datacenter
Same product in many platforms
Healthy open-source ecosystem
Should we always use Java? When Java?
7
Real-time or Critical Safety might not be indicated…
Depends on the use case! (easy answer)
Java doesn’t normally fit in small processors…
… but I’d use it anywhere possible!
Where can you use Java? Where Java?
On the Datacenter - whole software stack
On the field - Gateways and Mesh Nodes
Where can you use Java? Where Java?
Cinterion Concept Board - Java ME
• 3G EHS8 M2M module incl. GPS
• Application processor with Java-support (J2ME 3.2)
• Board extension connector • Arduino-styled connector • Integrated user buttons
and LEDs • USB-powered
Where can you use Java? Where Java?
RaspberryPi - Java SE Embedded
• BCM2837 Application (ARM) Processor and SOC Development Board
• 1200MHz CPU 1GB RAM • Linux/Win 10 OS • Board extension connector • USB-powered
Where can you use Java? Where Java?
Intel Edison - Java SE Embedded
• Intel SoC (x86): dual core, dual threaded Intel Atom CPU at 500MHz
• 40 GPIOs • 1 GB LPDDR3, 4 GB EMMC, • Dual-band WiFI and BTLE • Linux/Win 10 OS • Board extension connector • USB-powered
What are you connecting? What to connect to Java?
It depends on what you project is about, but…
• Sensors: • Light sensors • Temperature • Camera
• Switches
Find all these in the vendors (later on the slides)
Where are you connecting? Where to connect your Java?
You should start with the well known protocols and servers
• Oracle IoT CS • IBM Bluemix • Eclipse Kapua • Dweet.io
• Which you can use to create dashboards on Freeboard.IO
What are Java technologies you can use? What Java?
Open Source for IoT Eclipse IoT provides the technology needed to build IoT Devices, Gateways, and Cloud Platforms.
