Actually lwIP was first designed to work without an OS and was next reworked to run in its own thread using a simple callback through message box mechanism to keep it lightweight. > Anyhow, if there are some examples of this particular scenario (NO_SYS = 1, > everything within the main loop), kindly let know. It would save some time > ticks for us :) Again, lwIP contrib Git (and/or lwIP contrib releases) is more than complete with comprehensive NO_SYS=0 and NO_SYS=1 examples. Sylvain
