That’s were ill start then, I have attached a Wireshark trace if you can gleam any more information form it.

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<mailto:lwip-users-bounces+mike.danby=ascendx....@nongnu.org>> On Behalf Of Sergio R.
