Issues Finding Bluetooth Bee in Blueterm

Post by darwinwalters » Mon Jun 17, 2013 1:51 am

I am trying to set up a Bluetooth connection with an Android tablet and an Arduino using a Bees Shield and a Bluetooth Bee. I am currently using BlueTerm and this sketch:

Code: Select all

#include <NewSoftSerial.h> //Software Serial Port
#define RxD 9
#define TxD 10
#define DEBUG_ENABLED 1
NewSoftSerial blueToothSerial(RxD,TxD);
char incoming;
void setup()
{
 pinMode(RxD, INPUT);
 pinMode(TxD, OUTPUT);
 setupBlueToothConnection();
 pinMode(4, OUTPUT);
 pinMode(5, OUTPUT);
 pinMode(6, OUTPUT);
 pinMode(7, OUTPUT);
}
void setupBlueToothConnection()
{
 blueToothSerial.begin(38400); //Set BluetoothBee BaudRate to default baud rate 38400
 delay(1000);
 sendBlueToothCommand("\r\n+STWMOD=0\r\n");
 sendBlueToothCommand("\r\n+STNA=SeeeduinoBluetooth\r\n");
 sendBlueToothCommand("\r\n+STAUTO=0\r\n");
 sendBlueToothCommand("\r\n+STOAUT=1\r\n");
 sendBlueToothCommand("\r\n +STPIN=0000\r\n");
 delay(2000); // This delay is required.
 sendBlueToothCommand("\r\n+INQ=1\r\n");
 delay(2000); // This delay is required.
}
//Checks if the response "OK" is received
void CheckOK()
{
 char a,b;
 while(1)
 {
 if(blueToothSerial.available())
 {
 a = blueToothSerial.read();
if('O' == a)
 {
 // Wait for next character K. available() is required in some cases, as K is not immediately available.
 while(blueToothSerial.available())
 {
 b = blueToothSerial.read();
 break;
 }
 if('K' == b)
 {
 break;
 }
 }
 }
 }
while( (a = blueToothSerial.read()) != -1)
 {
 //Wait until all other response chars are received
 }
}
void sendBlueToothCommand(char command[])
{
 blueToothSerial.print(command);
 CheckOK();
}
void loop()
{
 // get character sent from Android device
 incoming=blueToothSerial.read();
 // decide what to do with it
 switch (incoming)
 {
 case '1':
 digitalWrite(4, HIGH);
 blueToothSerial.println("pin 4 HIGH");
 break;
case '2':
 digitalWrite(5, HIGH);
 blueToothSerial.println("pin 5 HIGH");
 break;
case '3':
 digitalWrite(6, HIGH);
 blueToothSerial.println("pin 6 HIGH");
 break;
case '4':
 digitalWrite(7, HIGH);
 blueToothSerial.println("pin 7 HIGH");
 break;
case '5':
 digitalWrite(4, LOW);
 blueToothSerial.println("pin 4 LOW");
 break;
case '6':
 digitalWrite(5, LOW);
 blueToothSerial.println("pin 5 LOW");
 break;
case '7':
 digitalWrite(6, LOW);
 blueToothSerial.println("pin 6 LOW");
 break;
case '8':
 digitalWrite(7, LOW);
 blueToothSerial.println("pin 7 LOW");
 break;
 }
 delay(100);
}


However, whenever I try to search for the Bluetooth Bee in Blueterm, the device does not show up.

Earlier on, I accidentally put power and ground connections in the 'GND' pins on the Bees Shield board (I don't remember since I removed the wires immediately). This caused part of my circuit to smoke, but I couldn't determine where it was coming from. The power light on the Bees Shield is still on, and I switched out the Arduino, but I still can't seem to establish a connection.

I'm sure that everything is set up correctly, jumpers are in the right place, etc. Did anyone else have any problems setting up this kind of connection? Will I have to replace some parts?
