i need some help with arduino - bluetooth shield

hi everybody!
(excuse my English, I use the google translator xD)
I am noob in arduino and I purchase a bluetooth shield to comunicate arduino with my cellphone (android 2.2). I read some topics about bluetooth comunication with xbee shield, but I cant understand how configurate the bluetooth shield, I know that is maybe basic, but I can’t with the tutorial.
i put the bluetooth shield on the arduino board
i connect the arduino with the computer through usb cable
i open the arduino software and the example “slave” and when i try to load it in the board, throws the following error

In file included from Slave.cpp:31: C:\Documents and Settings\Administrador\Escritorio\proyecto\arduino-1.0\libraries\NewSoftSerial/NewSoftSerial.h:71: error: conflicting return type specified for 'virtual void NewSoftSerial::write(uint8_t)' C:\Documents and Settings\Administrador\Escritorio\proyecto\arduino-1.0\hardware\arduino\cores\arduino/Print.h:48: error: overriding 'virtual size_t Print::write(uint8_t)'

appreciate any help.
I want to do (to star) is a radio controlled vehicle through a cell phone with android.

Thanks for your time

Did you install the NewSoftSerial library?
You can follow the wiki to connect with the PC,but we have not any software to use with Arduino and Bluetooth bee yet.

#3

Are you using 1.0 or 0.23? I tried with 1.0 and didn’t work but 0.23 is working

#4

Both of 1.0 and 0023.But library is not share with each other，so you need to install again in Arduino 1.0 library to use the code.

#5

thanks for the quick answers!!
I download the 0023 version and was able to load the example “slave” without problems. I can only doubt the bluetooth on the computer, because I have windows xp and really do not know how to add bluetooth devices.
I really appreciate your help.

hi everybody! (again!)
the things have been going great lately with Arduino / Bluetooth Shield, but I had some problems with the computer’s Bluetooth device (minor things) but no luck transmitting data.
I am using the following code for the arduino (is the adaptation of one I found on Instructables)(to control the motors I’m using an equivalent circuit "L298 Dual H-Bridge Motor Driver":

[code]#include <NewSoftSerial.h> //Software Puerto Serial BT
#define DEBUG_ENABLED 1
#define RxD 6
#define TxD 7

NewSoftSerial BTSerial(RxD,TxD);

int m1_c = 3;
int m1_d = 4;
int m1_pwm = 5;
int m2_c = 11;
int m2_d = 12;
int m2_pwm = 10;

int DatoLeidoBT = 0;

void setup()
{
Serial.begin(9600);
pinMode(RxD, INPUT);
pinMode(TxD, OUTPUT);
setupBlueToothConnection();
pinMode(m1_c, OUTPUT);
pinMode(m1_d, OUTPUT);
pinMode(m1_pwm, OUTPUT);
pinMode(m2_c, OUTPUT);
pinMode(m2_d, OUTPUT);
pinMode(m2_pwm, OUTPUT);
digitalWrite(m1_pwm, HIGH);
digitalWrite(m2_pwm, HIGH);
parar();
delay(500);
}

void loop(){
if (BTSerial.available() > 0) {
DatoLeidoBT = BTSerial.read();
BTSerial.print("Recibi: ");
BTSerial.println(DatoLeidoBT);
Serial.print("Recibi: ");
Serial.println(DatoLeidoBT);
delay(10);

if (DatoLeidoBT == 119){
  adelante();
  delay(25);
}
else if (DatoLeidoBT == 97){
  izquierda();
  delay(25);
}
else if (DatoLeidoBT == 100){
  derecha();
  delay(25);
}
else if (DatoLeidoBT == 115){
  atras();
  delay(25);
}
else {
  parar();
  }
}

else {
parar();
}
}

void adelante(){
digitalWrite(m1_c, HIGH);
digitalWrite(m1_d, LOW);
digitalWrite(m2_c, HIGH);
digitalWrite(m2_d, LOW);
}

void atras(){
digitalWrite(m1_c, LOW);
digitalWrite(m1_d, HIGH);
digitalWrite(m2_c, LOW);
digitalWrite(m2_d, HIGH);
}

void derecha(){
digitalWrite(m1_c, HIGH);
digitalWrite(m1_d, LOW);
digitalWrite(m2_c, LOW);
digitalWrite(m2_d, HIGH);
}

void izquierda(){
digitalWrite(m1_c, LOW);
digitalWrite(m1_d, HIGH);
digitalWrite(m2_c, HIGH);
digitalWrite(m2_d, LOW);
}

void parar(){
digitalWrite(m1_c, LOW);
digitalWrite(m1_d, LOW);
digitalWrite(m2_c, LOW);
digitalWrite(m2_d, LOW);
}

void setupBlueToothConnection()
{
BTSerial.begin(38400); //Set BluetoothBee BaudRate to default baud rate 38400
BTSerial.print("\r\n+STWMOD=0\r\n"); //set the bluetooth work in slave mode
BTSerial.print("\r\n+STNA=ArdubotBT\r\n"); //set the bluetooth name as “ArdubotBT”
BTSerial.print("\r\n+STOAUT=1\r\n"); // Permit Paired device to connect me
BTSerial.print("\r\n+STAUTO=0\r\n"); // Auto-connection should be forbidden here
delay(2000); // This delay is required.
BTSerial.print("\r\n+INQ=1\r\n"); //make the slave bluetooth inquirable
Serial.println(“The slave bluetooth is inquirable!”);
delay(2000); // This delay is required.
BTSerial.flush();
}

[/code]
after upload the code, I open the program SSCOM32E and try send data to the arduino but does not react.
one could guide me a little how I can transmit data from the computer COM port of the bluetooth device
I would greatly appreciate your help!
