DF-Bluetooth V3

[Ricky]

After a week test and research.  We do find lots of serial software do not support this bluetooth serial port.

One works for us is the hyper terminal which can read and write data.

Try this .

Hello admin!

Regardless what serial software I am using to watch what is happening at serial port, the bluetooth module should be capable to get paired with other devices like a phone or a computer.

Is there some point to consider to get a successfull connection with other device?

Thanks.

The bluetooth module can be set as Master or slave.

the default mode is slave mode which can be found by your computer and mobile phones. 

You can try to pair the bluetooth module use your phone, we've tested HTC, nokia, iphone without any problems.

Also, the computer pair has been tested recently both on windows 7 (32 and 64 bits) with success.

Hello!

Ok, I "pair" the bluetooth module with my laptop, my sony ericsson, a blackberry; there is no problem. The problem is the bluetooth module seems no recognize any bluetooth device. I said that because I have never seen the famous Link LED on.

Certainly, I have a curiosity: how independent is the bluetooth module from arduino? I assume the negotiation about pairing with other device is done only by the bluetooth module, without intervention of arduino so the bluetooth module has to pair with other device regardless I am using serial functions in my program? Am I wrong? (obviusly you use this module for serial connections with a program using serial functions but it would be interesting know the independenceof the module from arduino).

Thanks.

The Bluetooth itself has nothing to do with Arduino. It is a stand-along product which is just the same as all other bluetooth device.

The link led will only on when you actually open the serial port which actually turn on the bluetooth. The pair stage is just some pre-stage.

So, basically, you will need a software which can talk to you bluetooth.  For example,  http://www.amarino-toolkit.net/   is working excellently with Andriod mobile phone.

For winodws, you will need a software such as hyper terminal to open the serial port which will then actually turn the bluetooth on.

Hello!

Is there some way to configure the bluetooth module with "no pairing code needed"? It would be easier if the bluetooth module don´t require authentication and connects with the device I want.

Thanks.

Hey guys I'm new at this, but I tried so hard to communicate my Arduino UNO with a bluetooth Mate Gold and I can pair the Bluetooth with computer but just can't make the bluetooth comunicate with arduino. I'd also tried with NewSoftSerial. The problem is that I can comunicate the arduino when it's wired to computer and It works perfectly but the bluetooth just do not work !!! Can anyone help me here's my code:

**I almost forgot it I used Processing and the IDE for Arduino and I'd tried with every single BAUN value I can

***este es el codigo del software processing
//import class to set up serial connection with wiring board
import processing.serial.*;
//import cc.arduino.*;

Serial port;


//button setup
color currentcolor;
RectButton rect1, rect2;
boolean locked = false;

//println(Arduino.list()); //hace lo mismo que serial.list
  //set up window
  size(200, 200);
  //color baseColor = color(102, 102, 102);
  color baseColor=color(0,0,0);
  currentcolor = baseColor;

  // List all the available serial ports in the output pane.
  // You will need to choose the port that the Wiring board is
  // connected to from this list. The first port in the list is
  // port #0 and the third port in the list is port #2.
  println(Serial.list());

  // Open the port that the Wiring board is connected to (in this case 1
  // which is the second open port in the array)
  // Make sure to open the port at the same speed Wiring is using (9600bps)

Hi admin..

I just wan't to ask...

can bluetooth v3 used on ARM ST microelectronic(STM32F103)?

and how to pairing with other bluetooth v3?

please help

[Hector]

Hi,


You can use the Bluetooth V3 with anything else that uses a serial port (TTL, UART). All it needs is


GND
Vcc
Tx
Rx


Pairing for 2 modules is a bit difficult but it can be done through a serial terminal like putty.
