Re: [lwip-users] Recv UDP Problem

[Sergio R. Caprile]

It depends on what you actually do when you "use" the sockets.
If you trust your port and driver, then debug your app and do a traffic 
capture. Is it possible your app is starving the lwIP task as Noam 
suggests ? Where do your messages get lost ? Are they in the wire ? Do 
they enter the lwIP stack ? Is your driver priority higher than your 
task ? Do you have enough memory ? Enough pbufs ? Have you tried 
enabling stats to see if your driver is dropping frames because of no 
mem ? What is your application timing, how fast are your messages 
coming/going ? Do you lose consecutive ones ? Are you testing on a real 
network with traffic or do you have a one to one wiring ?
