The document discusses the integration of Eclipse and Lua for Internet of Things (IoT) applications, emphasizing the complexities of Machine-to-Machine (M2M) communication and the need for simplified programming environments. It presents various tools and frameworks available for M2M development, highlights the capabilities of the Lua programming language, and outlines a prototyping process for IoT applications using MQTT and other technologies. The conclusion notes the ease of developing M2M applications with the Mihini framework and the support provided by Koneki for application development.

- 34. Let me show you!
- 35. Step 1 – Early prototyping • Greenhouse business – Connect gardening equipments to each other – Remote monitoring of sensors – Remote control • M2M Gateway not selected yet, neither is the rest of the equipment (PLCs)
- 36. m2m.eclipse.org MQTT broker Raspberry Pi Mobile phone Modbus RTU humidity temperature illuminance light ON/OFF
- 37. Two Lua applications Embedded Mobile Corona SDK – Uses Modbus library – Subscribes to MQTT to talk to Arduino PLC messages – Collects sensor data/ – Displays sensor data controls actuators with a fancy UI – Publishes MQTT – Publish command to messages switch on/off the – Subscribe to light commands
- 38. M2M Developer Kit • Actual hardware early in the dev. process is key Affordable! Simple! Industrial! • http://wiki.eclipse.org/Mihini/Developer_Kit • Arduino code & schematics available after the conference
- 39. Step 2 – Use an industrial gateway • Need for rugged, industrial-grade M2M gateway • Take the Mihini codebase and compile it against the gateway’s toolchain • Mihini porting layer – straightforward for Linux-based devices with AT modem – porting layer for other solutions
- 40. m2m.eclipse.org MQTT broker Rugged Mobile phone wireless gateway Modbus RTU humidity temperature illuminance light ON/OFF
- 41. Step 3 – Industrial deployment • Use a real PLC – Mihini dev. kit is replaced by a real PLC – Only the configuration of the application (modbus registries #) will have to be updated • Use a reliable, multi-tenant, M2M server
- 42. Telco! M2M server Billing! etc…! Rugged Mobile phone wireless gateway Modbus RTU humidity temperature illuminance light ON/OFF
- 43. Conclusion • Developing an M2M app with Mihini is simple – Demo app written in a couple hours • Mihini apps are portable • Mihini itself is easily portable – make install • Koneki provides support for editing, debugging and deploying M2M apps
- 44. M2M AT ECLIPSE IS ALSO…
- 46. An all-in-one IDE • June 2013 • Ready-to-use • Market Place
