Good morning,


As we talked last week this can be either a driver problem. The low level code that reads and writes

to the hardware MAC or your LwIP settings.


You first must find the cause for that before you add your own code.

Subject: [lwip-users] ping slow down




I have built simple example, just lwip with freertos, no other tasks. I am observing that ping response normally around 1ms regularly in intervals approximately 60sec gets slower to 150-200ms. Then, it continues again at 1ms. See attachment.

So far I don’t see a problem with that but is there an explanation for such a behavior?
