PyQt5 on Mac, Virtual Com Port Example

hi

im new to qt, id like to learn pyqt5. my goal is to make an application for both macOS and Android, a simple windows with buttons that then send data to a serial com port (bluetooth).

is there anywhere a similar application?

so far im only able to run the hello world:

Code:

---

#!/usr/bin/python3
# -*- coding: utf-8 -*-
 
"""
brew install pyqt python python3 qt sip pip3
pip3 install pyqt5
pip3 install pyserial
 
run with python3 hw.py 
"""
 
import sys
from PyQt5.QtWidgets import QApplication, QWidget
 
 
if __name__ == '__main__':
 
    app = QApplication(sys.argv)
 
    w = QWidget()
    w.resize(250, 150)
    w.move(300, 300)
    w.setWindowTitle('Simple')
    w.show()
 
    sys.exit(app.exec_())
