Over the last few years, open source has become the “default” way of building software. Currently, the world of open source is witnessing a plethora of innovations at a considerably high pace. Many of today’s business models are built around free, open source technology. As a result, enterprises are adequately providing support on various open source components and are increasingly shifting their workloads towards open data architecture.
In our previous tutorials on IoT, we covered how to setup a Raspberry Pi and how to connect it to Parse Server using Back4App API to save objects to the server and to perform Queries and Live Queries.
Now we cover how to reproduce everything done on the Raspberry side to the App side. In this tutorial, we describe an Android App to interact with the IoT device configured earlier. From the Parse Server side, the App does the same tasks as the Raspberry: writes objects and performs Queries and Live Queries. Please note these functionalities may be useful even if you do not plan to develop an IoT application!
Parse has proven to be an amazing framework to crate IoT applications. In 2020, with the addition of the GraphQL API protocol it provides an even better way to retrieve data.
