 Have you ever dreamt of a ready-to-use platform to make prototyping of an IoT application rapid and effective without having to write any code? Well, ST makes your dream come true! Sensortile.boxpro is the solution. I am the Nissan Flippo Application Development Engineer in Memsug Group at ST, and I'm going to introduce you the first working mode of Sensortile.boxpro, known as the Entry Mode. The Entry Mode enables you to discover the Memsensors functionalities by providing predefined IoT and wearable functions and examples. You can connect your Sensortile.boxpro via Bluetooth by using the ST BLE Sensor app, available both on Google Play and on App Store, on your smartphone, and immediately build your own apps through a graphical interface. Let's go into detail. First of all, let's switch on the board and open ST BLE Sensor app on your smartphone. From the main page of the app, click on Create a new application and select Sensortile.boxpro as board type. A list of example apps categories appears. Select for example Motion. Then select Sense of Fusion Quaternion among the example applications. A brief description of the application and an app overview, schematized as application input, function, output are provided for each example application. If we focus on the Sense of Fusion Quaternion application, the LSM-6, DS-V-16X, IMEMO-6 3-axis, inertial measurement unit and the LIS2-MDL 3-axis compensated magnetometer are used to show the orientation estimation of Sensortile.boxpro in the 3D space. If we look at the block diagram of this app, the accelerometer sensor, gyroscope sensor and the compensating magnetometer are present. The compensating magnetometer is itself an application where the magnetometer is calibrated to compensate its offset. The output of the compensation can be saved. The Sense of Fusion Quaternion function is applied to this input data and the output is streamed to Bluetooth. Now click on Play button, available in the application overview section. The available board list appears. The considered board is identified by its name, in this case stb underscore pro. Click on Play. A pop-up window called Overwrite Board opens. To load the current application on the board, substituting the old one already present, click OK. The application is loaded and the blue LED turns on. A pop-up window appears. If you click on Boards List, you can go to the list of the available boards and select Yours. Otherwise, by clicking on Auto-Connect, you can directly connect to the board. Well done! Here it is MemSensorFusion Quaternion demo. If I move the Sensortile.boxpro, the dice is moving accordingly. This is amazing, isn't it?
