Is anyone can help me ? I don’t understand why i cant change my arduino name , baud rate , etc…
- First of all , I installed my Arduino Mega ADK with a Mega shield and i installed the bluetooth shield on it.
- After, I connected with wire the TxD0 to Rx3 and RxD0 to Tx3.
- I plugged the arduino USB to my PC , (windows named it COM3)
- I detected bluetooth and install it with the binary code ‘1234’
- COM4 and COM5 are reconized by my pc and now they are the port for the bluetooth.
- I downloaded software serial library and bluetooth library
- I tried this slave code on arduino.exe 1.0.x :
[list] - /
BluetoothShield Demo Code Slave.pde. This sketch could be used with
Master.pde to establish connection between two Arduino. It can also
be used for one slave bluetooth connected by the device(PC/Smart Phone)
with bluetooth function.

#include <SoftwareSerial.h> //Software Serial Port

void setup()
{
Serial.begin(9600);

{
char recvChar;
while(1){
if(Serial3.available()){//check if there’s any data sent from the remote bluetooth shield
recvChar = Serial3.read();
Serial.print(recvChar);
}
if(Serial.available()){//check if there’s any data sent from the local serial terminal, you can add the other applications here
recvChar = Serial.read();
Serial3.print(recvChar);
}
}
}
void setupBlueToothConnection()
{
Serial3.begin(38400); //Set BluetoothBee BaudRate to default baud rate 38400
Serial3.print("\r\n+STWMOD=0\r\n"); //set the bluetooth work in slave mode
Serial3.print("\r\n+STNA=SeeedBTSlave\r\n"); //set the bluetooth name as “SeeedBTSlave”
Serial3.print("\r\n+STOAUT=1\r\n"); // Permit Paired device to connect me
Serial3.print("\r\n+STAUTO=0\r\n"); // Auto-connection should be forbidden here
Serial.print(“PassChanged”);
delay(2000); // This delay is required.
Serial3.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.
Serial3.flush();
} [/list] - Then , I pressed « RESET » button.
- I dont understand why it dont work (im a programming college students and i didnt know where i am wrong, i’m entirely new with electronic systems)
- Here is a picture of the settings of my card.
Sorry for my bad english and thanks for advance
