Telit and Java ME Embedded 8

By Terrence Barr, from his original blog

In case you missed it, Telit and Oracle last week published a customer solutions brief titled:

Telit Brings Internet of Things Technology Faster to the Automotive Market and Other Industrial Sectors Thanks to Embedded Software Platform

Key quote:

“Oracle Java SE Embedded and Oracle Java ME Embedded are the perfect platform for our 3G and 4G wireless IoT communication modules. “

Java ME Embedded is especially well suited for enabling robust and secure intelligence on the edge in resource-constrained or deeply embedded devices and is being successfully adopted across a number of use cases and industrial sectors, from remote monitoring and industrial control, to automotive and M2M communications. 

Find the solutions brief here (French version here).

Connecting Devices in the Cloud for Healthcare

Want to know how to create a useful IoT application using cutting edge technologies?  Join Gerrit Grunwald in our next VTS. He will walk you through a multi-faceted application designed for the elderly. Gerrit Grunwald takes a detailed look at use cases for the daily activities and schedules of the elderly to monitor any irregularities remotely and identify emergencies. Living in remote areas, many aging relatives are isolated and far away from medical facilities and doctors. 

He uses a mobile phone and a smart watch with a Java based gateway, iBeacons and other sensors to monitor their activity. He explains in great detail how the data is collected, aggregated, analyzed and visualized using the latest in technology.  With the help of an IoT cloud service this data can be analyzed to detect situations that are critical. 

VTS is a series of interactive online events with hands-on sessions and presenters answering technical questions. The events are sponsored by the Oracle Technology Network (OTN). They are free events but you must register. Join the next exclusive events near you: 

  • Americas - September 16th- 9:30am to 12:30 PST - Register 
  • EMEA - September 23rd - 9:30am to 12:30pm BST - Register
  • APAC - September 30th- 3pm to 6:30pm AU/SYD - Register

Check out IoT at JavaOne!

"We are always creating new IoT applications and encouraging others to improve them. Lhings is the networking tool that let us make it very easy. This time we wanted to make something we use in our everyday lives which is traditionally non-technical, as is a table, to be connected to the Internet and then provide new services that could be useful in some applications" explains José Pereda, who is part of the Lhings team. Based in Spain, the team won aJavaOne trip during IoT Developer Challenge.  

"We wanted to show that IoT is useful in real scenarios and it's accessible to anyone. Likewise, we would like to encourage developers to reproduce and improve it!" further explains José. You will get a chance to meet them at JavaOne.  

In the Internet of Things session track at JavaOne, you will learn about Java Embedded and discover great applications. Register today with the Flash Sale code DFS4, you will save US $400   

José is also presenting four talks at JavaOne

  • JavaFX 3D: Advanced Application Development
  • How to Build the Game 2048 with JavaFX and Java 8: Lessons Learned
  • Debugging and Profiling Robots with James Gosling
  • Create the Game 2048 with Java 8 and JavaFX

Challenge Ends on Friday!

This is your last chance to win a JavaOne trip. Submit a project video and code for the IoT Developer Challenge by this Friday, May 30.  12 JavaOne trips will be awarded to 3 professional teams and one student team. Members of two student teams will win laptops and certification training vouchers.

Ask your last minute questions on the coaching form or the Challenge forum. They will be answered promptly. Your project video should explain how your project works. Any common video format such as mp4, avi, mov is fine.

Your project must use Java Embedded - whether it is Java SE Embedded or ME Embedded - with the hardware of your choice, including any devices, boards and IoT technology. The project will be judged based on the project implementation, innovation and business usefulness. More details on the IoT Developer Challenge website 

Just for fun! Here is a video of Vinicius Senger giving a tour of his home lab, and showing his boards and gadgets.

Create Apps with the Gemalto Concept Board

"The Gemalto concept board has 2G and 3G support, so you can send text messages, place a call, write Java Midlets and Arduino shields support" explains Vinicius Senger.

In this video, he presents step-by-step tutorials on how to configure the Gemalto boards and to create a project controlling LED lights. You can download this project as well as the fan caller demo here. Visit the IoT Developer Challenge website for more training videos. Once you have a working project, submit a video and the code of your project for a chance to win a JavaOne trip! 

In the video below, Vinicius explains how to create a fan caller

Compete in the IoT Developer Challenge!

Show the world your embedded Java + Internet of Things (IoT) application for a chance to win a trip to JavaOne 2014! 12 winners will receive a trip to JavaOne 2014, the #1 place to meet world-renowned Java experts. In addition, six students will receive laptops and certification vouchers. Team up and submit the video and code of your project  by May 30, 2014.

Don't know how to start? We are providing eight free online training sessions in March and April. They will introduce you to embedded Java Embedded, IoT, Raspberry Pi and more. Everyone who registers gets a chance to win a Raspberry Pi starter kit.  

Need just a little bit of help? We will provide experts along the way -- regular "office hours." Ask questions on the Challenge forums and check the online resources. There may be some source code and solutions you can use for your project.  

At previous developer challenges, we've had developers:

  • Connect a doorbell to a camera, taking a picture and sending it to a cell phone when someone rings the doorbell.
  • Help blind people figure out which recycling container to use ("put it in the blue can" doesn't help!)
  •  Control a toy monster truck from a phone (Monster Truck As A Service!) 
  •  Connect a heart monitor to Google glass so your doctor or trainer can see your heart rate.

This short video shows them in action: 

Entries will be judged based on their implementation, innovation and usefulness:

  • Quality: a well-implemented project that uses Oracle Java Embedded with computer boards, devices or IoT Technologies
  • Innovation: a new and innovative way of using Java Embedded.
  • Usefulness: a project that meets a business need.

Internet of Things (IoT) Hackathon in Brazil

SouJava is running a Raspberry Pi and Java hackathon at Campus Party, the week-long technology gathering of geeks, developers, gamers, scientists, and students in Brazil. Sponsored by Oracle Technology Network, the hackathon is designed for enthusiasts who want to create IoT projects with Raspberry Pi and Java. The objectives are for attendees to learn, practice, and innovative while creating an IoT project

Java evangelist Angela Caicedo opened the hackathon with an overview of IoT and Java development. Over two days, participants will build teams, brainstorm, attend training, get a kit from the organizers and hack on their own project. Onsite experts will be available to help participants. They are veteran Java developers of web, enterprise and embedded development. Among them are GlobalCode founder Vinicius Senger, senior developer Rubens Saraiva, SouJava leader Bruno Souza, Java Champion Yara Senger, product manager Bruno Borges and senior mobile developer Ricardo Ogliari

Interview about Leap Motion with Geert Bevin

"The Leap Motion controller is a tiny device that measures the position of your hands in 3D space and it gives you a bunch of information so you can do things with that data." explained ZeroTurnaround Senior Engineer Geert Bevin. He created an application that allows users to make music with their hands; another that maps a series of gestures for keyboard and mouse commands for games. He showcased how to use it to control a computer and a game.
