Hi Nick,
I mean that we can either use hardware serial pins or Software serial , so whenever I'm trying to connect the Tx pin in either mode the Arduino board does not respond. Not even my first part of code which is just blinking of LED doesn't work
I'm using WS6318 GSM module
After removing the Tx pin (ie SoftSerial pin) the board runs my 1st part of the my code which is just blinking of LED.
