[lwip-users] tcp_write

[Jonas L]

I'm trying to send a chain of data using tcp_write. It seems like when I call
tcp_write twice bad things happen. Packet is never transmitted though both
calls return with ERR_OK.

That means that the only way to send data that is not in one piece is to
send a small piece, wait for it to transmit then call tcp_write again when
the first part is away.

Is this normal, and is there any solution except copying to one piece?
