NDK socket error question.

Anatoly Odler

Hello,

I'm working with C6748, NDK 2.20.05.33, BIOS 5.41.11.38.

We are developing a network application between the PC to DSP.

I have received an error (-1) while sending data through a socket. The send() API returned number of bytes less then requested. The fdError() returned (-1).

On which type of error or what is the description of the error(except no file descriptor session opened on a specific socket) occurred when the fdError() function returns -1?

Thank you.

What type of socket (TCP or UDP)?

It is TCP.

This error indicates that you did not call fdOpenSession() in the Task that is making the send call.

But I did do it. The program has called send several times successfully, and then returned -1.

Can be another problem with this?

What size is the packet that you are sending? What value is being returned from send()? What about the packets that were previously sent?Were they bigger, smaller or the same size?

What is the remote side doing?

What do you see going out on the wire (you can view with WireShark)?

What are the statistics showing? Look in A.18 of the NDK Reference Guide for details.

Hi,

I'm sending a fixed size of data on every cycle in a while loop.The size of the array I'm sending is 150Kb. The PC host just receiving the data, no more. Actually, when the error of (-1) occurred, the send API returned less bytes, then needed.

Anatoly,

Can you attach an sample program (both the .cfg and source files). Can you attach the PC source code also.

Thanks,
Todd
