'How to develop a Bluetooth DSP Android app easily to communicate an Arduino microcontroller?
I am completely new to Android app development. I am planning to develop a simple Android app to communicate with the Bluetooth module of my Arduino Board for processing the EEG data collected with some DSP technique like the Butterworth lowpass filter from the microcontroller. Python has a built-in dsp library (scipy.signal) but not in Java. For developing an android app, there are a lot of examples and recipes I can follow and learn with Java. As I am new to both app development and writing Java on DSP applications, I am not sure should I use Python or Java. My approach is to show a filtered EEG graph on the phone. Does anyone have good advice on where to start and the language I should use? I think I should use Android studio with Java but not sure how to deal with the part for signal processing. The board I am using is nRF52840, which has a Bluetooth module.
