[lwip-users] Problem with handling multiple client data

Hi,

I have a system (non-RTOS) that is set up as a server and has multiple clients connected (at present only 2).

As recommended for non-RTOS systems, I am polling for Ethernet input and am using TCP raw API.

When a single client is connected the system works fine but when 2 clients are connected, intermittently I get a problem.

The problem appears to occur when commands from both clients arrive at the same time, the responses to the separate commands get returned to one client rather than to the originating client.

As the code is linear and Ethernet packets are not being received under interrupt, I cannot see how this can occur.

Has anyone had a similar problem or advise me where I need to look for the possible cause of the problem?

Many thanks,

Tony
