ETH w5500 problem #21

Closed paoloSantinelli closed 3 years ago

paoloSantinelli commented 3 years ago

Good Morning,

I have downloaded picsimlab and compiled (cross compiled the win version in to Ubuntu) the experimental version to try the new spare part ETH w5500.

1) I have attached an Arduino Uno to w5500 and have run the telent client example. The windows machine running picsimlab has IP: 192.168.1.22, while I have statically assigned the IP 192.168.1.240 to the w5500 (I have even tried with 192.168.1.22); 2) On a machine (192.168.2.214) on the same network I have used netcat listening on port 2000 for incoming TCP connection. echo "Hello" | nc -l 2000

3) When Arduino try to connect, the connection is established but it is immediately closed (RST) by picsimlab;

This is what I have the captured using wireshark about the network activity:

2 192.168.1.214 192.168.1.22 TCP 66 2000 → 51004 [SYN, ACK] Seq=0 Ack=1 Win=64240 Len=0 MSS=1460 SACK_PERM=1 WS=1024

3 192.168.1.22 192.168.1.214 TCP 54 51004 → 2000 [ACK] Seq=1 Ack=1 Win=2102272 Len=0

4 192.168.1.214 192.168.1.22 TCP 60 2000 → 51004 [PSH, ACK] Seq=1 Ack=1 Win=64512 Len=6

5 192.168.1.22 192.168.1.214 TCP 54 51004 → 2000 [RST, ACK] Seq=1 Ack=7 Win=0 Len=0

This is the message on the Arduino Serial Terminal:

connecting... connection failed

disconnecting.

BTW. The w5500 web server example seem to work perfectly!

Any help will be appreciated.

Thank you very much

Hi Paolo,

I'm sorry, I only tested the ETH w5500 on Linux. The ETH part w5500 is not yet in the experimental stage, it is in the development stage yet (which is done in Linux). I develop everything myself and normally I don't have time to test everything, any help is welcome. I fixed the problems in relation to sockets in non block mode on Windows (93a53bb0ce7cc9185ac98fbb3c784d2ec46f9a71), but I haven't tested all the examples. In Linux all examples from the Arduino Ethernet library work. Your simulation should now work on windows. Any problem just let me know.

Hi

you don't have to apologize! Thank you very much for your great work!

I am going to test the code now.

Thank you again!

paoloSantinelli commented 3 years ago

Sorry,

it seems the problem is still there.

But I am new to github so.... I have removed the old cloned pixsimlab folder from my linux machine, then I have cloned and build again:

git clone https://github.com/lcgamboa/picsimlab.git cd picsimlab ./picsimlab_build_w64.sh exp

Did I do some mistakes... Maybe I miss something ??!!

Thanks and Sorry again

Paolo

Apparently you did everything right. I tested the corrections in Linux using wine, I will actually test in windows to check.

paoloSantinelli commented 3 years ago

Thank you again

lcgamboa commented 3 years ago

I run the PICSimLab on windows and fixed the bugs on TCP connection. I have tested three examples and all working now. Test if your code work with the last fix.

paoloSantinelli commented 3 years ago

Hi,

Yes! I have just tested, it seems to work perfectly!!

I tested it on the same machine (Arduino client with ETH w5500 and netcat server on the same VM) and even with netcat server running on a different machine.

Thank you Again!!
