Hi,
First of all read the lwip readme and every document you can find.
Check the echo server example and see how it is written.

If both servers are the same write functions and simply pass parameters. You do
not need
to copy and paste the same code. Use the arg parameter in the call backs

In the initial post, he said he's using 2.0.2, not 1.4.1 (what's that 1.41

OK, now I'm confused. In the accept callback, he compared the local port to see
for which port the incoming connection was.
I don't see what's wrong there?

Hi,
Do you mean two connections that you initiate from your device to two different
IP's
or two connections in a server ?
Your question is not clear ?

Hi,
I apologize myself.
I (uC) am the server and I initiate two connections with IP_ADDR_ANY but
different ports.
The PC is the Client and from here I connect to the Server.

Hello,
I am using lwip 2.0.2 RAW API and I have a question depending multiple TCP
Connections.
I create two connections without problems. Over each of them I can send and
receive data.
When a single client sends me data every 1ms, my receive callback function
(tcp_recv(pcb, myCallback1)) gets
So there are two separate servers with each handling one connection, correct ?
So what is the problem ?
Every server should have its own pcb and every connection has its own separate
pcb
You are doing something wrong, check your code.

U are right, but I don't know where the mistake is. I can debug it and the
breakpoints in myCallback1 and myCallback2 are hit.
The also debugged the init_Server and the binding or listen gave no error.
Both connections are initiated correctly.
I do init:
void init_Server(void)
{
Simon,
I did this while working on my own code, was not paying attention
My mistake, I thought that pcb->local_port means working port while
pcb->listenr->local_port is the server port
OK :-(

OK, just to clarify this for anyone reading:
pcb->local_port of an accepted pcb is (by definition!) the same as the
listener's local_port!
