well, I write like this:
int test;
test = tcp_write(pcb, SndBuffer, SndBufferLen, 0);
and get this:
(my C# program always try 3 times)
When I send 384 bytes:
first: test = -6
Don't send
second: test = 0
Send correctly
When I send 768 bytes:
first: test = -6
Don't send
second: test = -1
Don't send
third: test = -1
Don't send
