The Slave bluetooh shield is unable to get LED turned on by Master bluetooh shield.
How do you fix this? Here’s the code:

/* Upload this sketch into Seeeduino and press reset*/
#include <SoftwareSerial.h> //Software Serial Port
#define RxD 6
#define TxD 7
#define DEBUG_ENABLED 1
String retSymb = “+RTINQ=”;//start symble when there’s any return
String slaveName = “;SeeedBTSlave”;// caution that ';'must be included, and make sure the slave name is right.
int nameIndex = 0;
int addrIndex = 0;
String recvBuf;
String slaveAddr;
String connectCmd = “\r\n+CONN=”;
SoftwareSerial blueToothSerial(RxD,TxD);
void setup()
{
Serial.begin(9600);
pinMode(RxD, INPUT);
pinMode(TxD, OUTPUT);
setupBlueToothConnection();
//wait 1s and flush the serial buffer
delay(1000);
Serial.flush();
blueToothSerial.flush();
}
void loop()
{
char recvChar;
while(1){
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);
}
}
}
void setupBlueToothConnection()
{
blueToothSerial.begin(38400); //Set BluetoothBee BaudRate to default baud rate 38400
blueToothSerial.print("\r\n+STWMOD=1\r\n");//set the bluetooth work in master mode
blueToothSerial.print("\r\n+STNA=SeeedBTMaster\r\n");//set the bluetooth name as “SeeedBTMaster”
blueToothSerial.print("\r\n+STAUTO=0\r\n");// Auto-connection is forbidden here
blueToothSerial.print("\r\n +STPIN=0000\r\n");
delay(2000); // This delay is required.
blueToothSerial.flush();
blueToothSerial.print("\r\n+INQ=1\r\n");//make the master inquire
Serial.println(“Master is inquiring!”);
delay(2000); // This delay is required.
//find the target slave
char recvChar;
while(1){
if(blueToothSerial.available()){
recvChar = blueToothSerial.read();
recvBuf += recvChar;
nameIndex = recvBuf.indexOf(slaveName);//get the position of slave name
//nameIndex -= 1;//decrease the ‘;’ in front of the slave name, to get the position of the end of the slave address
if ( nameIndex != -1 ){
//Serial.print(recvBuf);
addrIndex = (recvBuf.indexOf(retSymb,(nameIndex - retSymb.length()- 18) ) + retSymb.length());//get the start position of slave address
slaveAddr = recvBuf.substring(addrIndex, nameIndex);//get the string of slave address
break;
}
}
}
//form the full connection command
connectCmd += slaveAddr;
connectCmd += “\r\n”;
int connectOK = 0;
Serial.print(“Connecting to slave:”);
Serial.print(slaveAddr);
Serial.println(slaveName);
//connecting the slave till they are connected
do{
blueToothSerial.print(connectCmd);//send connection command
recvBuf = “”;
while(1){
if(blueToothSerial.available()){
recvChar = blueToothSerial.read();
recvBuf += recvChar;
if(recvBuf.indexOf(“CONNECT:OK”) != -1){
connectOK = 1;
Serial.println(“Connected!”);
blueToothSerial.print(“Connected!”);
Serial.write("1");
blueToothSerial.write("1");
blueToothSerial.print("1");
delay(2000);
break;
}else if(recvBuf.indexOf("CONNECT:FAIL") != -1){
Serial.println("Connect again!");
break;
}
}
}
}while(0 == connectOK);
}
