Re: [android-developers] bluetooth file transfer failure

In order to answer your question, we need to see the code where you create and set mmInstream, too. For all we know, you might have forgotten to connect it to any stream,

here  i am trying to send a file over bluetooth but its not sending any data.

here the main problem is that its not sending or receiving any data over the two devices but they are connected to each other.

<on configuring the bluetooth chat example.>

Sending code:

     File myFile = new File(message.toURI());

     Double nosofpackets = Math.ceil(((int) myFile.length() )/4096);

     System.out.println(nosofpackets);

     BufferedInputStream bis= new BufferedInputStream(new FileInputStream(myFile));

     byte[] send = new byte[4096];

     for(double i=0; i<nosofpackets; i++)

     {

          send = null ;

          a=bis.read(send, 0,send.length);

          Log.d("BluetoothChat", "data packet " + i);

          if(a==-1)

          {

              break;

          }

          mChatService.write(send);

     }

Receiving code :

    while((bytes = mmInStream.read(buffer))>0)

    {

    

    Log.d(TAG, "data is there for writing");

    bos.write(buffer);

    

    }
