Просто проблема с отправкой данных, собранных с датчиков в листе Excel на Raspberry Pi на устройство мобильного телефона. Код работает, но он не согласован, и существует много сбросов/сбоев подключения. Рекомендую исправить или альтернативные способы кодирования этого?if __name__ == '__main__':
path = r"/home/pi/Scans/"

ser = serial.Serial('/dev/ttyS0', 115200, timeout=1)
ser.flushInput()
ser.flushOutput()
while True:
line = ser.readline().decode('UTF-8').rstrip()
ser.reset_input_buffer()
