Using RX and TX on a program

Using Arduino Programming Questions
#1

Hello Guys and Girls,

I would like to know if I can use the native RX and TX pins on a program, and if so, how i adress they?

for example, as I start a bluetooth module, I write:

SoftwareSerial Bluetooth(10, 11); // RX, TX

for example.

There's a way to connect the RX and TX whithout use other pins? Using the originals RX and TX? How I would call SoftwareSerial?

Thanks a lot!

It’s called Serial or SerialX where X is a number;depends on your hoard.

Serial.begin(9600);
Serial.print("hello");

Note that on boards with a single hardware serial port, you must make sure that you do not receive from USB and bluetooth at the same time. It’s also advisable to add a 220 ohm resistor between the rx pin of the Arduino and the bluetooth tx pin.

This is incoherent, but you might find the following background notes useful
