[asheeshtripathi]

Issue Description

Configured srsUE and srsRAN_project gNB as per the srsRAN gNB with srsUE document. UE logs show nrof_harq_processes_for_pd not present and UE fails to initiate connect setup procedure.

UE console shows RRC connected:

Setup Details

Intel NUC-1: Open5GS and srsRAN_Project gNB using x310
Intel NUC-2: srsRAN_4G (srsUE)

Expected Behavior

The srsUE should attach to the network.

Actual Behaviour

With same srsRAN_project gNB and Open5GS core, COTS UE is able to do the attach and proceed upto PDU session response.

Steps to reproduce the problem

srsUE and srsRAN_project gNB as per the srsRAN gNB with srsUE document.

Additional Information

external clock is connected to UE but not gNB. ( However same gNB attach woroks fine with COTS UE)

It looks like you're running an older version of srsUE, can you update to the latest version of srsRAN 4G and try again?

[andrepuschmann]

We'll release a new version of srsRAN Project this week which will fix the issue you're seeing.

[asheeshtripathi]

Thanks @andrepuschmann, looking forward to it.

[andrepuschmann]

We've pushed the code to https://github.com/srsran/srsRAN_Project so please have a look again. There's also a new appnote describing the required steps in detail https://docs.srsran.com/projects/project/en/latest/tutorials/source/srsUE/source/index.html

Closing the issue. Please feel free to reopen if you still have problems.

Thanks @andrepuschmann .
