Bluetooth Shield + Arduino Uno not discoverable!

Please post code so we can help you.... or try this code this is what works for me you can add your code after the line that says....blueToothSerial.print(recvChar);
}

Code:

#include <SoftwareSerial.h>   //Software Serial Port
#define RxD 6
#define TxD 7
#define DEBUG_ENABLED  1
SoftwareSerial blueToothSerial(RxD,TxD);

void setup()
{
  Serial.begin(9600);
  pinMode(RxD, INPUT);
  pinMode(TxD, OUTPUT);
  setupBlueToothConnection();
 
}

void loop()
{
  char recvChar; 
    if(blueToothSerial.available()){//check if there's any data sent from the remote bluetooth shield
      recvChar = blueToothSerial.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();
      blueToothSerial.print(recvChar);
    } 
    // ADD YOUR CODE HERE
} 
void setupBlueToothConnection()
{
  blueToothSerial.begin(115200); //Set BluetoothBee BaudRate to (115200) the default baud rate is 38400
  blueToothSerial.print("\r\n+STWMOD=0\r\n"); //set the bluetooth work in slave mode
  blueToothSerial.print("\r\n+STNA=SeedBT\r\n"); //set the bluetooth name as "SeedBT"
  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
  blueToothSerial.print("\r\n+STPIN=0000\r\n");//set pin to 0000
  blueToothSerial.print("\r\n+RTPIN=0000\r\n");// ask to input pin
  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();
}

if this code doesnt work when uploaded to arduino with bt/module then there may be other issues. Post back success or failure and will try to help further
