 Have you ever dreamt of a ready-to-use platform to make IoT application prototyping fast and effective even if code development is not your cup of tea? Well, ST makes your dream come true. Sensortile.boxpro is the solution. I am Denise Sancrippo, application development engineer in ST Mem subgroup, and I'm going to introduce you to the second working mode of the Sensortile.boxpro, known as Expert Mode. Expert Mode allows you to create relatively simple applications for IoT Mem sensors and wearables without writing lines of code using a simple graphical interface. You can connect the Sensortile.boxpro via Bluetooth using the ST BLE sensor app, available on both Google Play and App Store on your smartphone and immediately create your own app through a graphical interface. Let's go into detail. First, let's turn on the board and open the ST BLE sensor app on your smartphone. From the main page of the app, click on Create a new app and select Sensortile.boxpro as the board type. A list of sample application categories appears. Click Expert View to create a new application. In the Custom Applications window, there are the previously created and saved applications. Click New application, select the accelerometer sensor as the input source and click Set Input. Now, click on the gear on the right of the Input section to change its parameters. For example, change the output data rate by setting it to 120 Hz. Click Save configuration in the Function section. Click Choose a function and choose FFT Discrete Fourier Transform DFT. By clicking on the gear on the right, you can change the number of frequencies to be produced. Here, it is set to 64 and save it by clicking Save configuration. At this point, click Choose output and select Stream to Bluetooth as the available output method. In this way, the data will be visible directly on a ST BLE sensor app. Click Save app, assign a name to the app, for example, Bluetooth FFT Accelerometer and click Finish. The saved app is available in the list of the custom apps. Now, click either the Upload button or the name of the application and then the Play button to load the application on Sensortile.box Pro. The list of available ports appears. Here, we click Play and then OK to override the previously uploaded application. When the application has finished the uploading, click Auto-Connect to connect to the Sensortile.box Pro board. For example, let's move the board at 5 Hz to stimulate Z-axis on the Accelerometer. The corresponding signal is plotted accordingly on the app. Your first app in Expert Mode is completed and ready to be used well done. Explore all the possible applications of the Expert Mode and visit the Sensortile.box Pro webpage on ST.com for further details.
