Smart Shutter | Setting up a BlueSMiRF with Software Serial and Arduino

I was recently accepted into a beta test for MIT dealing with a prototype Arduino board and their website. I’ll create a final post showcasing the completed project, but for step by step updates check out their website here, and my personal project page here. Now on to the tutorial.

I always reset my module after I dust it off for use, jussttt in case:

Because I know I’ll need to do this again, I’ve decided to take the time writing a post explaining how to get communication going between an Arduino and a PC using serial over bluetooth in windows 8.

First thing’s first, connect to your device, as stated in the title, I’m using a BlueSMiRF Silver from Sparkfun.

Pairing is very easy. From there, upload the following code to your Arduino and connect your board as dictated by the code.

#include <SoftwareSerial.h>
SoftwareSerial mySerial(10, 11); // RX, TX

void setup()  {
  Serial.begin(115200);
  Serial.println("Send Hardware");

  mySerial.begin(115200);
  mySerial.println("Send Bluetooth");
}

void loop(){
  if (mySerial.available())
    Serial.write(mySerial.read());
  if (Serial.available())
    mySerial.write(Serial.read());
}

#include <SoftwareSerial.h>

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

void setup() {

Serial.begin(115200);

Serial.println("Send Hardware");

mySerial.begin(115200);

mySerial.println("Send Bluetooth");

}

void loop(){

if (mySerial.available())

Serial.write(mySerial.read());

if (Serial.available())

mySerial.write(Serial.read());

}

NOTE: IN ORDER TO USE DIFFERENT SERIAL SPEEDS, YOU WILL NEED TO MANUALLY CHANGE THE BAUD RATE USING THE DEBUG MODE IN THE BLUESMIRF.

Then open your device manager and see how the bluetooth configuration went and how the ports were assigned:

For some reason, the lower COM port number is the correct one, I have no idea why. I’ll be using Putty to connect to the bluetooth COM port, the config is very simple:

From there, start typing in either console and it should all work!

Thanks for reading!

Hey! This post was written a long time ago, but I'm leaving it up on the off-chance it may help someone. Proceed with caution. It may not be a good idea to blindly integrate this code or work into your project, but instead use it as a starting point.
