As I said, if I send bytes faster, audio will start to play faster than it should.

As I said, if I send bytes faster, audio will start to play faster than it should.

Of course, if you try to add 255 samples to the buffer, and playSamples lets you know that it was only able to add 200 samples to the buffer, and you forget to try again later to add the remeining 55 bytes, then audio will (seem to) start playing faster,

Show me code, which handles the return value of playSamples. And I'll tell you whether that is correct.

Currently it is not handled yet (just simple if statement , that prints out something if its less than 255. I will try to handle it now.

I hit very weird issue: As long as PC only have output stream and NXT only have input stream, communication works.

But If I create input stream on PC or output stream on NXT, communication will not work (NXT will freeze on .readByte() and PC will freeze on .flush().

This prevents me from NXT signaling PC when is ready to receive sound.

I assume this is using USB? That seems very strange. You certainly can not on the PC side have one thread reading while another writes, but it is very common to have both input and output streams with USB connections. P,lease post a short sample that demonstrates the problem.

When I init both DataInputStream and DataOutput stream:

PC:

Code: Select all

      DataOutputStream output = new DataOutputStream(new BufferedOutputStream(connector.getOutputStream(), 5000));
        DataInputStream input = new DataInputStream(connector.getInputStream());

NXT:

Code: Select all

DataInputStream input = new DataInputStream(new BufferedInputStream(connection.openInputStream(), 4000));
       DataOutputStream output = connection.openDataOutputStream();

NXT will stall on readByte() method and PC will stall on flush() method. This is without even using any NXT -> PC code. If I comment out DataInputStream on PC and DataOutputStream on NXT, it strangely works. I have to comment out both (If I for example just comment out DataInputStream on PC, but leave DataOutputStream on NXT it will not work).

I think you need to create a set of small test programs that shows the problem and post them here. That way we can take a look at what is going on....
