How to use Serial Communication - but NOT with the TX and RX pins

Projects Programming

Hi all,

I'm new to this forum and this is my first question.
I am using an Arduino Nano and due to physical space constraints I can only connect my bluetooth module to the board using the 6 ICSP programming pins. I understand that they are connected to pins 11,12,13, Vcc, Ground and RESET.
So what I'm asking if I can initialise Serial Communication between my bluetooth(connected to smartphone) and the Arduino Nano by using pins 11 and 12.

I don't know how to do this as the serial.begin command doesn't take pins as an input so I don't know how to change it from the default TX, RX pins to 11 and 12.

Thanks all

With this library you just chose any two pins on your Arduino to communicate via serial with your HC-05.

Those pins will be Rx and Tx.

ARDUINO DIRECTION OF DATA HC-05

Tx -----> Rx
Rx <----- Tx

The ICSP pins on an arduino are not for regular serial communications - it is a different thing entirely
