Can you also please provide the circuit schematic?
I'm unable to get RX TX signal from it using C++

if you bought LTE module from ktron.in then you should connect TX to TX and RX to RX.

That's odd. Yes. I bought it from ktron.
Generally we need to cross connect it right? Rx to TX and TX to Rx

yes but ktron done that cross connection in their PCB itself

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?
