Hi,

I'm sending data between a cell-phone and a PC via Bluetooth:

This works for strings and numbers when I explicitly set them (e.g. int
sendData = 3), but when I want to send data which is computed in the
follwing way, it doesn't work properly:

/* CLIENT */
// rawData.length is between 100.000- 2.000.000
int packetSize = 256;
int numPackets = (int)(rawData.length / packetSize);
byte[] packet = new byte[packetSize];
// write number of packets
ByteArrayOutputStream baos = new ByteArrayOutputStream();
DataOutputStream      dos  = new DataOutputStream(baos);
dos.writeInt(packetSize);
byte[] rawNumPackets = baos.toByteArray(); //write 4 byte
//send number of packets
connection.send(rawNumPackets);

/* SERVER */
byte[] rawNumPackets = new byte[4];
int length = connection.receive(rawNumPackets);
ByteArrayInputStream bais = new ByteArrayInputStream(rawNumPackets);
DataInputStream      dis  = new DataInputStream(bais);
int numPackets = dis.readInt();

So, the problem is the following:
When I compute on client side the value numPackets and print it out I
get an value of 542. This int value I send to my server, but here I
receive 434.
When I put on client side int numPackets = 542, then I receive on
server side 542.
This happens with every number.
That makes completely no sense to me!
Does anyone know what the reason for this could be?

Thanks,

Peter
