Mihini/EclipseCon2013 Tutorial

Tutorial

This tutorial "Develop a complete M2M application with Koneki and Mihini" occurred at EclipseCon 2013 on 2013-03-25.

Tutorial material

Tutorial material is hosted at https://github.com/SierraWireless/eclipsecon2013-m2m-tutorial

How to get it:

  • Clone git repository
   git clone https://github.com/SierraWireless/eclipsecon2013-m2m-tutorial.git
   # to get the beautiful and correct look&feel for the slides
   git submodule update --init
  • download zip file:
https://github.com/SierraWireless/eclipsecon2013-m2m-tutorial/archive/master.zip

Once you've got the repo locally, you can browse tutorial material:

Especially:

  • slides: at the root of the repo
    index.html 
  • Code Solution:
    lab/mihini-tutorial-step3/

(That's a Koneki project, so can import it directly in your IDE)


Goals

Show Mihini

  • show key APIs such as logging, sched, airvantage, devicetree, (sms?)...
  • show how it's easy to do I/O manipulation and wireless communication

Koneki for Mihini

  • show how Lua is easy to edit thanks to LDT tooling
  • show EE and remote development for Mihini

FUN!!!!!!

Hardware

The main hardware will be a Raspberry Pi (running Mihini) connected to an Arduino ; the Arduino itself being connected to several sensors/actuators.

Bill of materials

This is the minimal list of materials to reproduce the demo:

Item Qty
Raspberry Pi 1x
Arduino Uno 1x
Grove kit or equivalent 1x
Micro USB cable 1x
4GB SD card 1x
USB 1A power supply 1x
USB A-B cable 1x

Compile and run Mihini manually

Installation of Lua Development Tools (all-in-one bundle)

Home of Koneki Lua Development Tools: http://eclipse.org/koneki/ldt/

Default version of Koneki doesn't come with Remote Target Management feature (that enables, for this tutorial, to connect to RaspberryPi system, send your application to it etc).

To create the all-in-one bundle that was provided during the tutorial, you have to: TBD


Setting up the Arduino

Arduino code used for the tutorial is -->

M3DA Server

An instance of M3DA server is running on Eclipse M2M machine.

To contact it with Mihini agent, you must use this address:

    tcp://m2m.eclipse.org:44900 

Run you own M3DA server instance:

Everything you need for that is there (How to build, to run, interact with):
