Bluetooth communication between Android and Arduino using Processing -

i trying make two-way bluetooth communication between android , arduino using processing android. have success transferring data android arduino serial.begin(9600). , have success transferring data arduino android using softwareserial in arduino program , bluetooth.begin(9600) in place of serial.begin(9600).

however, when trying transfer data android arduino using bluetooth.x commands, not work. here arduino code:

  if (bluetooth.available()) // wait until character received   {     char val = (char)bluetooth.read();     //serial.println(val);      switch(val) // perform action depending on command     {       case 'w'://turn light on when 'w' received       on();       break;        case 'q'://turn light off when 'q' received       off();       break;        //default://otherwise remain in previous state       //idle();       break;     }   } 

the on() , off() functions switch on , off led on arduino. mentioned, works when i'm using serial.x commands , not bluetooth.x commands. also, using ketai processing android. using processing 2.0.1, arduino 1.0.5, android 2.3.6.

here relevant beginning code:

#include <softwareserial.h> softwareserial bluetooth(0,1);  //tx 0, rx 1 

a little more code appreciated...

have included that?

#include <softwareserial.h>  int bluetoothtx = 2; int bluetoothrx = 3;  softwareserial bluetooth(bluetoothtx, bluetoothrx); 

edit:

that's similar use. first upload code without bluetooth wired , wire bluetooth. can use serial.dosomething() because using same pins, don't need #include <softwareserial.h>. need make sure baudrate same.

you can try code make sure works fine:

void setup(){      serial.begin(9600); // or wathever bluetooth module baudrate  }  void loop(){      serial.println("hello world!"); // make sure works.     delay(500);  } 

you should make sure you arduino connected computer via bluetooth.
