Sometimes when i call send()method it give me: java.net.SocketTimeoutException: Connection setup failure: socket closed during operation.

Hi,
Could you share how you use send() (with the ByteBuffer or the ByteArray)?

About the second exception, it is explicit: the socket has been closed.

Hi,
in my java android project ,when,i used send(ByteBuffer) it give me java.net.SocketTimeoutException: Connection setup failure: socket closed during operation.
when i used send(ByteBuffer.array()) it give me Operation not supported: Incorrect use of Message API (sendmsg/recvmsg).

when i used srtSocket.getOutputStream(null).write(buffer.array()); it is ok.

but in your kotlin project,all is ok.

when i call send() method，then the socket been closed. Not socket been closed ,then call send() mistake. I test many times,and also see the server.

So, you don't face the first issue anymore?

I believe the only issue you face is that you are trying to use message API with an incorrect size of buffer. Either:

• use a buffer with the correct size
• use stream API
  Please refer to the SRT documentation for more info.
