Hey guys,
not sure if this is the right place for this question, but it involves an example code so maybe it is.
for a project of mine, of i have an older arduino mega 1280 connected to a blue smirf gold from sparkfun: http://www.sparkfun.com/products/158
however, with the example code provided with arduino 1.0, i can't get anything to show up in the bluetooth serial port(using putty for the bluetooth port)
does anybody have an idea as to why the bluetooth would be seemingly not working? I have the hardware connections exactly as they say in the sample code:
RX(bluesmirf)-->TX(pin 3)(arduino)
TX(bluesmirf)-->RX(pin 2)(arduino)
VCC(bluesmirf)-->3.3v arduino mega
ground-->ground

Code:

/*
  Software serial multple serial test
 
 Receives from the hardware serial, sends to software serial.
 Receives from software serial, sends to hardware serial.
 
 The circuit:
 * RX is digital pin 2 (connect to TX of other device)
 * TX is digital pin 3 (connect to RX of other device)

#include <SoftwareSerial.h>

SoftwareSerial mySerial(2, 3); // RX, TX

void setup()  
{
 // Open serial communications and wait for port to open:
  Serial.begin(57600);
   while (!Serial) {
    ; // wait for serial port to connect. Needed for Leonardo only
  }

  
  Serial.println("Goodnight moon!");

  // set the data rate for the SoftwareSerial port
  mySerial.begin(4800);
  mySerial.println("Hello, world?");
}

void loop() // run over and over
{
  if (mySerial.available())
    Serial.write(mySerial.read());
  if (Serial.available())
    mySerial.write(Serial.read());
}

Are you sure all 3 of the bluetooth module, the mega, and putty are set to talk the same baud rate?

[Reply #2 on:]

yes, arduino and putty are set to proper bauds.
bluetooth is auto-negotiation so there is no setup needed physically on the bluetooth, im pretty sure about that.

i have an older arduino mega 1280

which has 4 hardware serial ports. So, why are you using SoftwareSerial?

SoftwareSerial only works on certain pins on the Mega. I don't recall which pins they are, but I do know that
1) it isn't needed.
2) pins 2 and 3 are not supported.

Well I don't really plan on the mega being used on this project much longer.  I was either gonna use a dum. Or a pro mini.  But I hadn't thought about the fact that certain pins might not work for software serial on the mega.  So when I get home I'll have to try other pins or the other available uarts.  But I'm still not convinced that's the problem.  Because when I connect the bluesmirf to the pins 0,1 which are for the default "serial" connection I still get nothing.  So I still think its a bluesmirf hardware issue.  Unless I'm wrong on that too.
