Hello OmNetPP and simu5G users,

I have the same questions on this link: How to add an ethernet port to a simu5G UE?

What I am trying to do is directly add an Ethernet interface in NRUe.ned and establish a Ethernet link between UE and TSN device in the main network file (TSN_5G.ned).

However, the following error message pops up: No submodule 'ue[1]' to be connected, at /home//Simu5G/simulations/NR/networks/TSN_5G.ned:107 -- in module (omnetpp::cModule) TSN_5G (id=1), during network setup

Can someone give me some hints to solve the problem? Thank you and best regards.

My codes are as follows:

Expected to happen: The simulatoin can run.

Actually resulted: A error during network setup

  • Hi, I see that the above UE is still not able to forward packet through the ethernet port. Did you get it working? – Piper Feb 08 '23 at 23:33

You've set *.numUe = 1 in your ini file as well as ue[numUe].ethg++ <--> Eth1G <--> tsnDevice1.ethg++; --> ue[1].ethg++ <--> Eth1G <--> tsnDevice1.ethg++; in your ned file. As a consequence: 1) you're not connecting all your modules from vector, only ue[1], 2) you're going out of range since the only element presented in your vector is ue[0].

Try to change ue[numUe].ethg++ <--> Eth1G <--> tsnDevice1.ethg++; to:

for i=0..numUe-1 {
    ue[i].ethg++ <--> Eth1G <--> tsnDevice1.ethg++;
}
