Andre,

I had a similar problem when I tried to broadcast over UDP. I wanted a client to broadcast and a server to reply. AFAIK Revolution cannot do that. I solved it by having the server open a new connection to the client. Since you're sure that the client will reply, this can be a normal connection, which allows you to keep the connection open as long as necessary.

Best,

Mark

Folks,

I have two stacks, one is a udp server stack and the other is a client stack. The server is setup to use the newPacket callback message when a datagram arrives. The client will write to the server then it will read from the socket to see if there was any answer.

The client is able to write to the server fine, the datagrams arrive nicelly. The server is not able to answer back, no error is reported by the write to socket message but nothing is returned to the server, the read from socket message after the write to socket on the client returns empty. I've sent more than 1k packets, they could not be all droped since on one way it all works fine but on the other way they simply don't work.

Am I doing something really stupid?

My packet size is 576 chars, I've also used 8k and 2k sizes, the client is able to send those fine and they arrive intact, but from server to the client I can't seem able to communicate.

thanks in advance, udp is kinda new to me.
