When an interrupt comes from the ring indicator pin, I want to read the message from the UART without interrupting your internet connection, just suspend it and then activate your internet connection again.
I can disconnect the connection with ppp.active(False) and read the message from the UART, but; ppp.active(False) this time the internet connection is lost.
I am connecting to a socket server. If the internet connection is lost, I have problems when I connect again due to the nature of my project.
uart = UART(_id, baudRate=_baudRate, rx=_rx, tx=_tx)
uart.write('+++');
time.sleep(3);
uart.read() => None
Can you help me?
