Setup Guide

Please read the README first.

Use the QUICKSTART guide for local testing.

1. General configuration

1.1. Ports

  • Receiver Port (from vehicleCAPTAIN routing core): 5555
  • Sender Port (from vehicleCAPTAIN routing core): 5556
  • Local Exchange Port (between sender and receiver examples): 5557

BE AWARE: the vehicleCAPTAIN routing core receives/sends messages via its connected V2X interfaces. There is no direct feedback loop.

1.2. Run SENDER Demo Software

The IP is either:

  • IP of the sending routing core (sending vehicleCAPTAIN)
  • IP of the receiver demo (127.0.0.1, with network bridge enabled)
  ./docker_demo_build_and_run
  docker exec cpp_sender-demo ./cppSender <ip> <port> <msg_id> <frequency (1/10Hz)>

2. Development Environments

The dev docker can be used for development. Below are two examples on how to integrate it with CLion. Other IDEs may be configured similarly.

2.1 Option 1: Remote Host

This configuration can be used when the IDE supports SSH remote deployment.

2.1.1 SENDER Setup

  • git clone CPP-Sender repo
  • in root folder execute docker script: 
    ./docker_dev_build_and_run.sh

2.1.2 Configurations in CLion

  • the docker has to be running, otherwise the connection is going to be refused

  • make the following configurations either for sender or receiver

    Toolchain Configuration
    • File -> Settings -> Build, Execution, Deployment -> Toolchains
    • Click "+" and "New Remote Host"
    • Configure new remote (SSH Configurations):
      • Host: localhost
      • Port: 2222
      • Username: user
      • Password: password
    CMake Configuration
    • File -> Settings -> Build, Execution, Deployment -> CMake
    • Click "+" and name it "Debug-Remote" for example
    • Select the previously created toolchain
    • Reload the CMake Project (open CMake file in CLion and click Reload CMake project)

2.1.3 SENDING messages

docker exec -it cpp_sender-dev ./cppSender <ip> <port> <msg_id> <frequency (1/10Hz)>

2.2 Option 2: Docker Connection

This configuration can be used if the IDE allows direct docker access.

2.2.1 SENDER Setup

  • git clone CPP-Sender repo
  • in root folder execute docker script: 
    ./docker_dev_build_and_run.sh

2.2.2 Configurations in CLion

Toolchain Configuration
  • File -> Settings -> Build, Execution, Deployment -> Toolchains
  • Click "+" and "Docker"
  • Setting should look like this:
    • Server: Docker
    • Image: clion/lw_remote-cpp_sender-env:0.1
  • Click 'Apply' and 'OK'.
CMake Configuration
  • File -> Settings -> Build, Execution, Deployment -> CMake
  • Click "+" and name it "Debug-Docker" for example
  • Select the previously created toolchain
  • Reload the CMake Project (open CMake file in CLion and click Reload CMake project)

2.2.3 RECEIVING messages

  docker exec -it cpp_sender-dev ./cppSender <ip> <port>

In summary, a script creates a Docker with a working configuration, that can be connected to via SSH.

3. Hints for consecutive tests

  • the cpp_sender-demo docker has to run
docker start cpp_sender-demo
  • if the code has changed, the docker has to be built again
docker rm cpp_sender-demo
./docker_demo_build_and_run.sh
  • if the docker is built and running
docker exec cpp_sender-demo ./cppSender <ip> <port> <msg_id> <frequency (1/10Hz)>
  • if the ip address is already in use:
docker stop cpp_receiver-demo
docker start cpp_receiver-demo
