### Using the provided sample xApp
The sample xApp provided in this repository connects to the [SCOPE](https://github.com/wineslab/colosseum-scope) RAN environment through the following [E2 termination](https://github.com/wineslab/colosseum-scope-e2).
After the near-real-time RIC has successfully started, the DU connected to it, and the xApp has been properly configured and started (see "Quick start" section above):
- Enter the xApp docker container (named `sample-xapp-24` by default): `docker exec -it sample-xapp-24`
- Move to the right directory inside the Docker container: `cd /home/sample-xapp`
- Start the xApp: `./run_xapp.sh`. This script will open a socket between the sample script in the `sample-xapp` directory (which by defaults prints the data received from the RAN node) and the base station connector of the `xapp-bs-connector` directory. Then, the xApp will subscribe to the RAN node specified at contianer startup time through the gNB ID, and send a RIC Indication Message that triggers a data report from the RAN node with the periodicity of 1 second.
