Hi Sergio,
Thanks for your reply, and sorry for the delayed answer.
I attached a Wireshark capture file that includes the last 3 successful communication cycles and then the slowdown.
I am not running RTOS. NO_SYS = 1
This is a single-threaded applications and all the work is done in the callback functions (ie. accept callback, receive callback for gathering the numbers and then sent callback for populating the send buffer and sending its content back to PC).
And lastly could you give some more information about what to check in my driver to make sure that all the frames are processed not only the first one?
Thanks,
Márk Bartha
