Hello,
I try to use the lib iolibrary with a w5100 chip on a microchip pic32
I succeed to communicate with the chip and I resolve to connect to a tcp server on my computer (in python)
But I have a problem. I try to send a byte every 200ms. It seems to work on the begining and after I receive a lot of random data and I have a brutal disconnection.
On my python script I have this result
Python 3.8.1 (tags/v3.8.1:1b293b6, Dec 18 2019, 22:39:24) on Windows (32 bits).
This is the Pyzo interpreter with integrated event loop for ASYNCIO.
Type ‘help’ for help, type ‘?’ for a list of magic commands.

On my micrhip pic 32 I would like to send ‘U’ → 0x55
I have this code on my Microchip
wiz_NetInfo gWIZNETINFO = { .mac = { 0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xED},
.ip = {192,168,0,15},
.sn = {255, 255, 255, 0},
.gw = {192, 168, 0, 1},
.dns = {168, 126, 63, 1},
.dhcp = NETINFO_STATIC};
wizchip_setnetinfo(&gWIZNETINFO);
result = socket(0, Sn_MR_TCP, 1000,0);
uint8_t adr_ip[4] = {192,168,0,16};
result = connect(0,adr_ip,1000);
uint8_t test_buffer = 0x55;
result = send(0, &testBuffer ,1);
Sorry for my bad english…
