Would be interesting to see if a simple UDP unicast app worked. i.e. Is it UDP that isn't working, or broadcast that isn't working, or something else... > this is my complete lwipopts.h code: Looks OK to me. There was a bug concerning UDP broadcast recently: [bug #26309] Implement SOF_BROADCAST https://savannah.nongnu.org/bugs/?26309 but I think that was to do with receiving UDP broadcast frames rather than sending them. It might also be worth contacting the authors of the example you're using to see if there is anything special that is required to get it to work. Do you have any kind of debugging tools available on your lwIP device? The quickest way to get a solution to your problem would be to trace through the stack and see how far your packet gets. Once we know where it is dropped, the solution should be much easier.
