Yes, I was trying to provide the minimum code required to force the reset. I need the received UDP package in a string for further processing - hence the recv. How would you go about that?

Have a look at my example here, maybe it helps:

I tried this. It cuts off the last byte of the received UDP package and stops working in my environment. I am on windows 8.1.

If it cuts off the last byte you could change

Code: Select all    if (len > 0) packetBuffer[len] = 0;


into something like

Code: Select all    if (len > 0) packetBuffer[len+1] = 0;

Sure, that is not a bit issue. The bigger problem is it stops working after receiving 1 package..

The sketch is OK on my Mac.

Could the problem be caused by the program you use to send the UDP packet?

I use Packet Sender for testing (also available for Windows).
