App Usage

Here’s a short usage guide on the recording app. This uses the iOS version of the app, but it works similiar for Android, Linux, macOS and Windows.

1. When you open the app you will be greeted with the Xiao Connector screen. Tap on Connect to connect to the microcontroller.

   

2. To conserve power, the microcontroller enters a low-power mode upon Bluetooth connection, preventing automatic acceleration data recording. To access a live feed, manually activate it by tapping on Open Live Feed.

   

3. This is what the feed looks like when you are connected.

   

   A tap on Sync Clocks can be used to manually sync the clocks between the recording device and the microcontroller.

   To start recording, enter a name and then tap on the start button at the bottom of the screen.

   

   To stop the recording, tap on the button at the bottom of the screen again.

4. Now you can switch to the Recordings screen by tapping on the Recordings icon in the navbar. You’ll see your newly created recording that was stored on your device.

   

   Tap on it to see the details of the recording and to access the Export functionality.

   

5. The exported files will be stored in the documents of your device. Here we used an iPhone and we can find the exported recording data as a CSV file in the app’s folder in Files.
