I did the loopback demo applications and it works well, if there are any
further tests you would recommend please do elaborate. I am using RAW LWIP
here on an LPC43XX.
Here is my capture, the traffic is randomly generated data that I'm sending
from the PC copying in my APP and then sending back
Hello community, I am testing my implementation and have found that sometimes
I receive more than 1460 bytes at a time, and it appears to be duplicate
data. I know this because I am sending and receiving the data using a simple
python script and the payload has duplicate segments coming back to
PSA: It appears my issue was solved simply by using pbuf_cat instead of chain
on my receiving end. The receiving end of my stream is working.

Good afternoon LWIP users,
I could use a little help here, I'm attempting to take data from a pbuf
chaing and transfer it to an app buffer. What I'm doing is adding data to a
pbuf as I receive it, my app is aware of that object and will read off bytes

Thank you,
I have read that page, and actually lept ahead to 2.0.0, it was an easier
upgrade than I expected. Further, I was able to get a basic example working
sending a string through a client. For now I have only a couple of questions
to help me in my design. I need to expand this so that I
Precisely, a TCP client is exactly what I need. I'm looking at both the lwip
src and contrib for LWIP 1.4.0 and did not find one instance of tcp_connect.
The only ones I see that is related to raw tcp at all is a server and does
tcp_accept(echo_pcb, echo_accept); ... and similar in the http
Thank you Sergio, I realize that TCP is a one to one connection. However, I'm
honestly struggling to find an example that initiates the connection from
the embedded device. The echo sample project for example establishes a
passive connection that binds to an incoming connection (as I understand
