well, just to close the topic, i finally did it. the string was wrong, cause the same way packetsender does, we have to send a "mixed" string, with the values of the starters and so on in hexadecimal, but the data values in ascii. once the full string was "wrong", the connection wouldn't open...

update: after a few minutes looking at wireshark, i saw that device 2 is responding to computer requests. but it doesn't answer the device 1. how can it be? did i configure something wrong? all i have to do is set the ip's, subnets , ports and it should work. i mean, the commands i sent via...

no problem! device 1 is supposed to send hex values to device 2 via tcp/ip. that hex sequence have the values that define the whole commands that device 2 needs to refresh the internal values. i know that the sequence is right cause if i send them via PacketSender they refresh the internal...

@robertjo24 i already have wireshark. but how do i "sniff the traffic" in order to know if they are connected? ty edit: from 192.168.0.170 -> "64 Who has 192.168.0.180? [ ETHERNET FRAME CHECK SEQUENCE INCORRECT ] " well i guess they are not connected. :/

via ethernet crossed cable, with a switch. yet, all of them with static ip. and "connected" as if they can send messages/commands between them.

i already used angry ipscan but it only shows the ip's ( that i already know ). i "simply" want to know if device 1 and 2 are connected between them.. dunno why but i tried : ping -S 192.168.0.180 192.168.0.170 and the prompt says that "PING:transmit failed. General failure". idk what it means..

hey there, i have 2 devices connected to a switch, that is connected to my computer. IP's device 1: 192.168.0.180 device 2: 192.168.0.170 computer 192.168.0.175 . subnet masks 255.255.255.0 is it possible to ping from computer to check if device 1 is connected to device 2 ? if i ping them the...

hey there , i'm here just to close this thread. it works properly the way u all said it ! thank you !

Thank you @robertjo24 !! I was going to ask that too. Yet, i was already using the same subnet mask. At first i thought that DHCP would be automatic. Tommorow i'll try the way u say, like 192.168.1.10 and 192.168.1.20 . subnet mask 255.255.255.0 . I was using normal cables though. i'll make a...

Directly connected. That's why i don't understand the ping each other part. The devices don't have a cmd prompt .. they are programmed to communicate between them and to decode an output value(s) .

where does that help me? it's an honest question, i'm not being sarcastic!

hey there! i'm programming a device with internal scripting features ( basically it decodes some files, i just format the output content the way i want ) and i want to connect that device to another device that runs like a server application, to read the final output content. they're connected...
