Arduino Bluetooth Issue

i connecting ardunio via bluetooth bee (actually , seeedstudio 'bee') . anyhow , send command turn on/off led on pin 3 . problem having seems work 75% of time. can turn on , off have enter a/b several times , if 1 foot away device. hardware issue? please let me know if problems obvious in code , maybe delay?

thanks in advance!

code: [select]

#include <softwareserial.h>   
#define rxd 12
#define txd 13
#define debug_enabled  1
softwareserial bluetoothserial(rxd,txd);

int ledpin1 = 3;




void setup()
{
     
    pinmode(ledpin1, output); 
    pinmode(rxd, input);
    pinmode(txd, output);
    setupbluetoothconnection();

}

void loop()
{
 

  if(bluetoothserial.read() == 'a')
  {
    digitalwrite(ledpin1, high); 
    bluetoothserial.println(" led on pin 1 on");
  }
  if(bluetoothserial.read() == 'b')
  {
    digitalwrite(ledpin1, low); 
    bluetoothserial.println(" led on pin 1 off");
   
}



}


void setupbluetoothconnection()
{
    bluetoothserial.begin(38400);
    delay(1000);
    sendbluetoothcommand("\r\n+stwmod=0\r\n");
    sendbluetoothcommand("\r\n+stna=testmode\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);
    sendbluetoothcommand("\r\n+inq=1\r\n");
    delay(2000);
}


void checkok()
{
  char a,b;
  while(1)
  {
    if(bluetoothserial.available())
    {
    = bluetoothserial.read();

    if('o' == a)
    {
     
      while(bluetoothserial.available())
      {
         b = bluetoothserial.read();
         break;
      }
      if('k' == b)
      {
        break;
      }
    }
   }
  }

  while( (a = bluetoothserial.read()) != -1)
  {
   
  }
}

void sendbluetoothcommand(char command[])
{
    bluetoothserial.print(command);
    checkok();   
}

code: [select]

  if(bluetoothserial.read() == 'a')
  {
    digitalwrite(ledpin1, high); 
    bluetoothserial.println(" led on pin 1 on");
  }
  if(bluetoothserial.read() == 'b')
  {
    digitalwrite(ledpin1, low); 
    bluetoothserial.println(" led on pin 1 off");
   
}
if character in buffer b, first statement read it, , decide not a. next statement read next, possibly non-existant, character, , decide not b.

you need test there character read first. then, need read , store character. then, need test stored character. not read every time.
