Hi, thanks for pointing this out. After the last code release, we need to release also the new version of the app note. |

It sounds like this is a documentation issue with the new code release. Is there a known fix-action? |

We also had this issue with the latest updates. Also, when we tried running the testbed without flexric with the latest open5gs and srsran_project gnb and srsran_4g ue, connection could not be established. Is this a known issue? |

The problem is still not solved, however I found out, that when using the latest flexric version , at least the RIC does not crash when starting the srsRAN gNB. Follow the installation guide for flexric (I also needed to update swig to v4.1) And then build the project using these flags in the CMAKE command CC=gcc-10 CXX=g++-10 cmake .. -DE2AP_VERSION=E2AP_V3 -DKPM_VERSION=KPM_V3_00
make installAfter starting the open5GS core from the srsRAN docker and the nearRT-RIC I get this output (not crashing) in the RIC: This means, now the Functions with SM ID = 2 and 3 are known to the RIC and the srsRAN gNB is able to connect via E2 Interface. Here the output of the gNB: ./gnb -c gnb_zmq.yaml
The PRACH detector will not meet the performance requirements with the configuration {Format 0, ZCZ 0, SCS 1.25kHz, Rx ports 1}.

Type <t> to view traceHowever, when i start the UE now, i do not get a connection to the gnb via zmq - but this might be related to another issue - i dont know. Maybe this helps some of you guys - looking forward to hear from you, if anyone has the same issue or a solution for getting the UE connected. Update 08.01.2024 - ZMQ workingAfter copying the adjustments on the config files for gNB and UE from thread #350, I am now able to use the setup with zmq. |

Was the connection established when using USRPs? If so, do you mind sharing the gains on both gnb and ue, and the attenuation in between? |

@LVancina I tried adding the flags to the cmake and can verify that it works! I used the docker open5gs that srsran project provided (the open5gs version in it is v2.6.1) and used USRPs. Connection is established between gnb and srsue. I can also duplicate the failed connection issue using zmq. You are right that it may be related to something else. |

@pengnist It didn't work for me. I'm wondering if I am making a mistake by switching to the e2ap-v2 branch after cloning the flexric repo. Did you do that? If not, do you mind sharing which release tag you used and the values you used for the -DE2AP_VERSION=<e2ap_version> -DKPM_VERSION=<kpm_version> flags? |

I used the tag that @LukasWehrstein provided for cmake: CC=gcc-10 CXX=g++-10 cmake .. -DE2AP_VERSION=E2AP_V3 -DKPM_VERSION=KPM_V3_00. I didn't switch to e2ap-v2 branch. Instead, I used their master. |

I am facing the same issue, and using -DE2AP_VERSION=<e2ap_version> -DKPM_VERSION=<kpm_version> with cmake does not work |

Maybe double check if you are on flexric master branch. |

@LukasWehrstein Did you have all tests passed when running ctest? I had a few tests failed, but near-RT RIC was able to connect to gnb. |

Please check our updated tutorial, where the above issue was solved by using a newer version of Flexric. |

Hello @pgawlowicz, In this part of the upload: "Enable Enable RLC metrics reporting that will feed E2SM_KPM service model with measurements data: metrics: Do we need to add anything to the directory? Because when I run it, like adding that part to the gnb_zmq.conf, it gives this error: Then I run everything like the tutorial, but on the xApp, the metrics are 0 and the values of the timestamp are negatives, so I think there is an error on the part that is filling the E2 KPM message. Do you think it is better to open an issue, or is there something that is missing in the new tutorial? Thanks |

You need to use the newest release of the srsgnb (commit: 0b2702c). Then you need to start some traffic, e.g., with iperf: so there is some traffic to measure the DL and UL throughput > 0 |

Uh oh!

Greetings,
I am new to srsRAN and I am trying to get one of the example experiments from the docs up and running on my Dell Precision 7670 running Ubuntu 22.04. I followed all of the instructions found here: https://docs.srsran.com/projects/project/en/latest/tutorials/source/flexric/source/index.html, and I can start up the Open5gc core and FlexRIC without a problem, with the following output initially on the FlexRIC terminal
lucas@lucas-dell-research:~$ ./flexric/build/examples/ric/nearRT-RIC
Setting the config -c file to /usr/local/etc/flexric/flexric.conf
Setting path -p for the shared libraries to /usr/local/lib/flexric/

but, when I start up the gNB, I get the following output in the FlexRIC terminal:

For reference, this is what the ouput in the gNB terminal looks like:

Can anyone give me a hint about why I might be having this issue? I had this same experiment running just fine on a VM, but it's giving me problems now that I have a dedicated Linux machine.
Please let me know what further details might be helpful.
