Hi all,
I have a seeedstudio bluetooth (http://www.seeedstudio.com/wiki/index.php?title=Bluetooth_Shield) which works almost: connection to my linux pc is OK, I can send chars from the serial terminal connected to the arduino+shield, and the remote pc receives them; but the other way around it does not work: nothing is received on the arduino side.
The sketch I use is here (from an example):
#include <SoftwareSerial.h> //Software Serial Port
#define RxD 7
#define TxD 6
#define DEBUG_ENABLED 1
SoftwareSerial blueToothSerial(RxD,TxD);
void setup()
{
Serial.begin(9600);
pinMode(RxD, INPUT);
pinMode(TxD, OUTPUT);
setupBlueToothConnection();
}
void loop()
{
char recvChar;
while(1){
if(blueToothSerial.available()){//check if there's any data sent from the remote bluetooth shield
Serial.println("available!!");
recvChar = blueToothSerial.read();
Serial.print(recvChar);
blueToothSerial.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();
blueToothSerial.print(recvChar);
}
}
}
void setupBlueToothConnection()
{
blueToothSerial.begin(38400); //Set BluetoothBee BaudRate to default baud rate 38400
blueToothSerial.print("\r\n+STWMOD=0\r\n"); //set the bluetooth work in slave mode
blueToothSerial.print("\r\n+STNA=SeeedBTSlave\r\n"); //set the bluetooth name as "SeeedBTSlave"
blueToothSerial.print("\r\n+STOAUT=1\r\n"); // Permit Paired device to connect me
blueToothSerial.print("\r\n+STAUTO=0\r\n"); // Auto-connection should be forbidden here
delay(2000); // This delay is required.
blueToothSerial.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.
blueToothSerial.flush();
}
Any ideas?
TIA
