Unable to connect open5gs with gnb

[mireianogue]

Issue Description

The Open5gs and srsRAN are deployed on differents PCs. I am not able to see the connection between them. I think that the issue is coming from the amf bind addr of gnb. I need some help!! I have already followed the tutorials.

Setup Details

The Open5gs and the srsRAN Project are deployed/installed on differents PCs. Here are the configuration files:

Expected Behavior

I know that this is an example, but i except to get something like this in the gnb: And in the core (amf.log):

Actual Behaviour

Actually, i am obtaining on the open5gs:

And on the srsRAN_Project (gnb.log): gnb.txt.log

This is the gnb output:

Steps to reproduce the problem

1.How to configure the open5gs addr 2.How to configure the srsRAN_Project config file addr

Anyone has the same problem? I don't get where is the AMF being executed in the Open5gs PC or in the gnb PC?

[mireianogue]

I have solved the problem before.

But now I'm troubling with this:

The gnb log file is:

gnb.txt.log

Anyone knows how to solve "The PRACH detectro will not meet the performance requirments..."

[pgawlowicz]

Make sure the b210 usrp uses USB 3 connection. Probably you need to restart it.

Thank you! The problem it was the usb 2 connection. The message: The PRACH will not meet the performance ... still appears. Do you know if its going to be a problem when i connect an UE?
