Techorama 2017

IoT will be a total game changer. But how can the developer community leverage IoT technology? How can we reuse our existing development skillset in an IoT context? In this talk we will explain how we built an end-to-end IoT solution on top of the new Proximus LoRa IoT network and how TypeScript made our lives easier. We will first give a short intro about the three building blocks needed to build and IoT solution: • Sensor • Network • Application We will use our slotmachine demo application to zoom deeper into these building blocks and how we connected them. We will give you the highlights of the new low power long range Proximus LoRa network and what this means for you as a developer. The Proximus MySense sensor we used can be programmed using JavaScript. We will explain which APIs are available and how we leveraged our existing TypeScript and web development skills to speed up development. We will finish with our general architecture, integration with Proximus MyThings and our Node.js backend application written in TypeScript. This application uses web sockets to push the data to the frontend. This allows our solution to be push-all-the-way-up, pushing data from the sensor over the network to our application to our frontend, and deliver messages near real time.
