Arduino mega with ENC28j60

Using Arduino Networking, Protocols, and Devices
1

Hello everyone, ihave some project to connect arduino mega to ethernet connection using ENC28j60. iwant to simulate connection from 2 device that i have simulated in PC software simulation(local host). ihave recorded connection with wireshark.

iwant to make 2 arduino comunicating like in the communication above, please some advise or have the example for it. Thanks

2

i forgot that explain the connection
device 1 IP 127.0.0.1 PORT 57389
device 2 IP 127.0.0.1 PORT 5001
this is shared IP because recorded on localhost, but for real on 2 arduino mega the IP must different ithink

3

use EthernetENC library and see Arduino Ethernet library examples ChatServer and TelnetClient

4

hi Juraj,
ihave been search on the sample of ethercard library, but iam not found the syntax or command to do TCP hanshake like send or receive SYN PSH ACK FIN, iwant to simulate exactly communication like on the wireshark capture. Please your advise, Thanks

5

ethercard library doesn't implement standard Arduino networking API

6

Ok iwill dig in on EthernetENC library. are you have some example for tcp socket multiple packet?

7

you don't care about TCP packets on application level. you open a socket and write data.

8

how about tcp handshake?

9

what is TCP handshake?
the library has a TCP/IP stack which takes care of connection building, ACK, ...
but all this is in example mentioned in my first comment and in my Arduino SE answer
