To compile the project, please install the Android Studio first. Also you should install Android API 26(Android 8.0) or higher version.

Then launch the ECG Monitor App. The app should begin searching and connecting the bluetooth by itself. After it is connected, execute the sendwave.py program. The app should run normally now.
If you switch your device to landscape, touch your device to measure the wave.
