- Set default attach_timeout to 40s - Increase timeout only after failed attach attempts This modification addresses an issue in the RFSim-5G 2x2 test where the UE often fails to attach within the initial 20s window. The timeout may cause the UE to restart, which leads to two UEs appearing in the gNB log. By increasing the initial timeout to 40s, we avoid unnecessary restarts.
This document outlines how to use the OAI CI framework and gives a quickstart.

Quickstart
There is a script main.py that
- reads scenario files from XML
- executes the steps (e.g., deployment of CN/gNB/UE, attach, ping, ...)
To simplify, a script run_locally.sh can be used to run a single scenario
locally. First, download images for gNB&UE (we assume you already downloaded
the CN) and tag them "latest", which is expected by run_locally.sh:
docker pull oaisoftwarealliance/oai-gnb:develop
docker tag oaisoftwarealliance/oai-gnb:develop oai-gnb
docker pull oaisoftwarealliance/oai-nr-ue:develop
docker tag oaisoftwarealliance/oai-nr-ue:develop oai-nr-ue
Now, run the scenario:
cd ~/openairinterface5g/ci-scripts/
./run_locally.sh xml_files/container_5g_rfsim_simple.xml
Output should look like

it will run an end-to-end test, connecting one UE to the gNB, and ping, before
undeploying. As shown, logs will be under
/home/richie/oai/cmake_targets/log/container_5g_rfsim_simple.xml.d/. The
python code also produces an HTML report in ci-scripts/test_results.html.
Running with local changes
In order to run the tests as above, with local changes, please build images locally.
It is not yet possible to override an existing image with changes made locally to a source file and run it directly through the CI framework. However, it is possible to override an existing image with local changes, and run the scenario manually following the console logs steps provided above. This is described in the 5G RFsimulator README.
