QuestionBlueTooth Bytes Disappearing Pin
C-P-User-314-Mar-13 13:03
C-P-User-314-Mar-13 13:03 
My small box sends the same byte continuously to the PC across a bluetooth connection.

After successfully receiving about four thousand bytes (give or take a few hundred) no more bytes are seen. I am quite confident that the bytes (a whole lot more than four thousand) continue to be sent well after the stream disappears from the rest of the system.

I am highly suspicious that Windows is somehow, for some reason, not accurately giving these bytes to my app.

My suspicion has been heightened because my external transmitting box continued after I stopped the app. I restarted the app, and I got 941 "left over" bytes, from where, I don't really know (but my external byte generator had been silent for several minutes, so it was no longer sending data).

We then started the small box generating continual data again, and saw the same behavior: 4435 bytes were seen, despite a two minute flood of bytes at 921600 bps.


Here is the receive thread


C#
void RecieveThread()
 {
     int n;

     while (continueRecieving)
     {
         n = connectorPort.BytesToRead;

         byte[] bits = new byte[n];

         if (n > 0)
         {
             connectorPort.Read(bits, 0, n);
         }

         Write(bits);
     }
 }



Just in case anyone feels it's important, here is the Write(bits) routine

C#
public void Write(byte[] b)
{
    if (writting)
    {
        for (int i = 0; i < b.Length; i++)
        {
            storage[sPlace++] = b[i];

            pass += b[i].ToString("X2") + " ";

            if (sPlace % numericUpDown1.Value == 0)
            {
                pass += "\r\n";
            }
        }
    }
}




Has anyone previously experienced disappearing bluetooth bytes on a Win7 machine with a C# app ?
