SoftwareSerial with Mini pro 3.3v V1.0

I don’t seem to be able to read anything using the software serial on the serial input on my mini pro - I’ve even tried a simple loopback joining pints 2 and 3 together, and the outputting to the inbuilt serial but data is never shown as available.

Am I doing something obviously wrong??

This is the test loop I’m using

#include <SoftwareSerial.h>
SoftwareSerial nss(2,3);

void setup(){
// Start up serial ports
Serial.begin(9600); // used for debug ouput
void loop() {
if (nss.available()) {

I get the loaded message, but whatever I write or print to the port gets mimicked back.

Any ideas?


sorry - that last bit should have said 'DOESN'T get mimicked back.'

Is the same issue present using other pins? 2 and 3 are the external interrupt pins.


I ve got the same issue, i change pin and baudrate but nothing happen.
