updated the code. I found I was not doing the bind/listen/accept cycle correctly. Not sure I have it right yet, I still can't connect more than once. Hope someone could tell me where I am going wrong.

Great stuff!! Now it works!

Probably not the way to do it, but I got it to accept multiple connects by moving these 2 lines of code inside the while(true) loop in the Main()
Socket listenSocket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp); listenSocket.Bind(ep);
So the listening socket gets created and bound every time it finished a connection
No I can connect as many times to the Netduino as I want.

I would never have thought to do it that way. I am used to using sockets under WinSocks and you would not normally have to recreate the socket to get a new connection. It looks to me like it is not dropping the connection when I close the socket. Your solution causes the socket to be desposed and that may explain why it works.

We've updated the experimental Wiznet drivers to support TCP Server in addition to TCP Client and UDP. We enhanced performance a bit as well.
Updated drivers are attached to the first post in this thread.
[Please note that TCP server ports can only serve one client at a time. If anyone has been successful getting the Wiznet shield to support multiple simultaneous clients per port, please let us know as we would love to support that scenario.]
DNS support is not yet implemented, but you should be able to use the MFToolkit to resolve hostnames to DNS addresses.
Although these drivers are experimental, they are approaching release quality. If you experience any issues with them, please let us know so that we can tweak and refine...
Enjoy!
Chris
P.S. Everyone please join us in saying "thank you" to klotz for his contribution, laying the groundwork for the Wiznet TCP server functionality... We also used klotz's test app extensively during development.

Hi Chris,
great to read this.
Because I'm new to the community I don't know where to find the actual driver and maybe some sample code to test it. Can you tell me where to download this, please? I use the netduino and the arduino ICSP board. I got it yesterday and I'm very eager to start programming with it. Do I have to consider something? Will I have to bridge the CS pins to get the SD card working? The networking stuff should work without grater problems - I think.
Netduino is great. I like it very much.
Thanks in advance from Germany.
Cheers!
Stan

Hi Stan,
The experimental drivers are attached to the first post of this thread.
If you're using the Arduino Ethernet shield with the ICSP pins, be sure to solder a 6-pin header onto the ICSP area of the Netduino.
We'll enable simultaneous use of the SD card and Ethernet in the v4.1.1 beta firmware. Right now, you can use both (if you bridge the CS pin of the SD card to D10)--but not at the same time.

Hi Chris,
thanks for the quick replay. The netduino community is really great.
I soldered the ICSP pins yesterday at night and a small TCP Server is working now (test code was posted at this thread). It worked at once. Amazing!
I'll install 4.1.1 - I know it's a pre release and will test the behaviour of the SD card and TCP/IP.
Thanks again and regards to the netduino team

Hi Chris,
sorry, me again.
I flashed the new Firmware v4.1.1 but I can't get the sample working again - like with v4.1.0. SD card can only be reached if I'm not using network at the same time. Why is this? Is this because of the shield design. I bridged D4 and D10, too. No chance. I have the new shield design with the integrated micro sd socket on it. Networking is sometimes possible - sometimes not. Is the netduinoPlus the better choise if I want to do some logging over network or start a silverlight app from the sd card? Flash is so contrained with plus, that's the reason I bought a netduino with shield.
Are some samples available hwo to access SD with the new Firmware and how to handle network with the new stuff? And both together? Sorry for the Newbie questions.
Regards
Stan

Hi Stan,
Simultaneous use of networking and SD on the new Arduino Ethernet shield will be supported by the official v4.1.1 firmware, but isn't supported by the current alpha version. This will be supported by picking the "chip select" for the SD...a parameter that is currently ignored.
You can use both at the same time (and at much faster speeds) on the Netduino Plus today--no problems there.
Our next update to the v4.1.1 alpha firmware is scheduled for next week. I don't think that the final SD code will be in this one, but it should be in an upcoming beta.
Thanks for testing this!
Chris

Hi Chris,
thanks for the quick answer and the excellent support.
I thinks a netduinoPlus is missing in my collection.
Thanks again.

Has anyone verified if the drivers will work with LinkSprite CuHead WiFi Shield for Arduino http://www.cutedigi....6d911aa02c5caa0
Is is only $55 (cheaper than the other WiFi shields). I plan on using it with a regular NetDuino (not Plus).
Thanks!

Hello, I do not understand electronics and I'm starting with the development of netduino, I wonder if someone could tell me how to connect the Arduino Ethernet Shield in netduino with this breadboard.

Actually you don't need a breadboard. You can just stack the ethernet shield on top of the Netduino. Perhaps this wiki page gives a nice example of what I mean: http://wiki.netduino...on-shields.ashx

Hello Stefan, saving my life again, as you may have noticed I have asked questions in relation to RFID and LCD, if I connect the network card in netduino how I should connect the other components?

Just put a breadboard next to your netduino and use jumper wires to connect things together.Hello Stefan, saving my life again, as you may have noticed I have asked questions in relation to RFID and LCD, if I connect the network card in netduino how I should connect the other components?

Hi is there any update to the wiznet code ? This thread is quite old and I wonder if there has been any progress.

Hi Danny,
BTW, welcome to the Netduino community!

I believe that the experimental drivers are working pretty well. With the launch of the Netduino Plus, most users are using the integrated open source networking there...so these are here for the community.Hi is there any update to the wiznet code ?

Thanks for your welcome, I have a mini + wiznet system that I need to develop so unfortunately I need more fully implemented drivers [dhcp + wol] for my project and I was wondering if any progress was made before I begin re-inventing the wheel. Here is a picture of my project as it stands (IMAGE), As you can see I have a Wiznet Module and integrated PSU that I have used from an old arduino project that I built last year. I've just started with netduino so its all a bit new to me. I tried out a http server program found on this forum but it was throwing a socket exception, I really haven't spent much time deciphering the code yet so before I begin in ernest I thought I would check if there had been any improvements.

Hi Danny,
That looks like a cool project.
I don't believe that there is any planned managed code implementation of DHCP (since the Wiznet chip doesn't support it...we'd have to build the stack separately).
We are looking at supporting the ENC28J60 module though...which would provide a native networking option for the Netduino Mini.
Please post more photos or videos once you have your project up and running! Looks interesting!
Chris
