When the test program is run for the first 3-5 seconds the each send call will result is the string (approx. 15 bytes) being transmitted to the client in separate frames. After that (even though the calls to send continue at a rate of 1Hz) the strings start to get packaged up into single frames. The number of strings in the packaged frames grows on a few iterations to be around 20 -25 (frames around 300 bytes).
I also see the server respond to ARP requests, however the frame is 1514 bytes. The data in the ARP request is correct but Wireshark notes the "Ethernet Frame Check Sequence Incorrect", I assume (probably incorrectly) because the frame size incorrect even though data is good. -----Original Message----- From: lwip-users <lwip-users-bounces+mike.danby=ascendx....@nongnu.org> On Behalf Of Sergio R.
