hey there,

i need to send some hex strings via tcp/ip from device to device, directly connected, so i tried first to connect the server device to the computer and send the commands manually via PacketSender. The device opens connection after i send the commands and acts the way it's supposed to.

but when i connect the device that is supposed to send that commands , that are already formatted ( the string i used to test is one of the strings that the master device outputs ) , it doesn't open the connection. does packetsender adds extra content to the string? i don't have access to source codes to check this out.

After all this i installed wireshark and kinda traced what is happening. it shows a error "ETHERNET FRAME CHECK SEQUENCE INCORRECT" after asking for the device at 192.168.0.180( server device ip). i read before that this is normal when using wireshark. yet, after this, there's no connection open.

In conclusion, can someone explain how does packetsender works? i read that it uses mixed-Ascii.. but it shows the Hex values too. and i'm formatting the master device to output hex string too..

thank you!

PacketSender is not part of the Wireshark suite, you'll have to look for support for it over at their site.
