I will try it though I hope the amount of logs won't affect the result. while analyzing the wireshark captures I noted that the packet i supposed to capture arrives in a short time after the one before. for example, here is a time between the consecutive transmitted packets: 0.000050000 PKT 12201 0.000050000 PKT 12202 0.000050000 PKT 12203 0.000050000 PKT 12204 0.000050000 PKT 12205 0.000050000 PKT 12206 0.000020000 PKT 12207 ==> though this one was received at the app as "PKT 12202" 0.000050000 PKT 12208
note that the problematic case was transmitted in a very short time after its previous one. this is also the case in other problematic cases. is there any way to configure ethernet IFG (Interf Frame Gap)?
