Hi David Lee,

I would love to see your device driver code working for cs8900a crystal LAN chip. I am now upgrading from uip 0.9 to 1.0. However, the code that I am using right now does not make the uip communicate over the network properly i.e. something must have gone wrong somewhere!! Attached is my code for cs8900a device driver.

Cheers

HI there,

I’ve ported uip 0.9 to LPC-E2124 board by olimex. I found no problem with webserver demo provided in the package. However, when I try to make a simple uip_connect program that connect to a listening server, which I developed using Java eclipse, it turned out to be the listening server output an error message of “connection reset”. I have confirmed that there is no problem with the java server. I suspect the problem arose due to uip_checksum or uip_connect(??). The code is as follows:

#include "report.h"

#include "uip.h"

void report_init(void)

{

u16_t ipaddr[2];

            uip_ipaddr(ipaddr, 192,168,1,68);

            uip_connect(ipaddr, HTONS(1234));

}

void report_app(void)

{

            if (uip_connected() || uip_rexmit())

            {

                        uip_send("hi/n",3);

                        return;

            }

}

The problem arose as soon as I call the function report_init(). Don’t even have the chance to test the report_app(). Any body could help with this?

Have you tested the modified code? I think it cannot be done that way since the compiler outputs an error message: “incompatible types in assignment” at the line you modified. I use GNUARM GCC compiler. Is there any other suggestion?

Hi Neil,

I am currently using uIP 0.9 as well for my final year project. The only difference is I ported uIP on the top of FreeRTOS 4.0.

I have a problem with connecting to a simple listening server which I developed by using java server socket. As I made an attempt to establish a connection to the host server, the server returns an error message on the console of “connection reset”. I am not sure what the problem is. As far as I am concerned, the server works fine when I connect to it using MS telnet. Could you please let me know how exactly I can make a connection and hence transmit packets? And do you have a sample of source code on how it is done? What sort of server are you using? Finally here is my code for my simple client socket software:

#include "report.h"

#include "uip.h"

void report_init(void)

{

u16_t ipaddr[2];

            uip_ipaddr(&ipaddr, 192,168,1,68);

            uip_connect(&ipaddr, HTONS(1234));

}

void report_app(void)

{

            if (uip_connected() || uip_rexmit())

            {

                        uip_send("hi/n",3); 

                        return;

            }

}

Attached is the java code for my server. Could you please help me with this problem?

Thank you,

Hi,

I am using uIP 0.9 on a SPARC processor as part of my final year project.

At present I have the httpd example and a simple TCP receiver running, the connected port determines which process runs.

At present I can send TCP packets to the port the receiver is listening on and it can receive and process them fine.  However when I close the connection remotely I can never reconnect.

When the app is called there is a list of if statements relating to the uip_newdata(), uip_closed() etc. functions.  When the TCP connection is closed the uip_closed() function is true and the program prints “Connection Closed” to the console.  I have noticed however that this is always written twice indicating that the closed event occurs twice.  I have tried doing nothing when uip_closed is true and I have tried running uip_close() neither seem to work.

The httpd server allows disconnection and reconnection however.

Any ideas?

Many thanks

Neil Jeffery

Hi there,

I am having the same problem that u have had earlier. I guess u no longer having the problem to make your board as the client. Could you please help me on how to do so? Thank you.

Subject: [uip-users] example for active connect

Hello,

i´m trying to establish a connection between server and client with active open, but it don´t works. If my controller runs as server and i use the listen() function ist works. I want to my controller to be the the client and connect to a server.


Thanks for answers.
