A libcluon-based microservice for listening in on a multicast-based LWE450 network. This software does not perform any parsing or validation of the LWE450 messages, merely acts as a one-way bridge from a LWE450 transmission group to the libcluon group.

Each release of cluon-lwe450 is published as a docker image here and is publicly available.

Can also be used as a standalone commandline tool. No pre-built binaries are, however, provided for this purpose.

This repository makes use of CPM.cmake for dependency resolution as an interal part of the CMake setup. As a result, the only requirements for building from source are:

• a C++17 compliant compiler
• CMake (>=3.14)

As part of the CMake configuration step, the following dependencies are downloaded and configured:

• libcluon
• CLI11

To build (from the root directory of this repo):

cmake -Bbuild -DCMAKE_BUILD_TYPE=Release
cmake --build build -- -j 8

This repo contains some configuration files (in the .vscode-folder) for getting started easy on the following setup:

• Ubuntu 20.04 (WSL2 is fine)
• GCC 9
• python 3
• VSCode as IDE, using the following extensions:
  • C/C++ (ms-vscode.cpptools)
  • C/C++ Extension Pack (ms-vscode.cpptools-extension-pack)
  • CMake Tools (ms-vscode.cmake-tools)
  • Python (ms-python.python)

Do the following steps to get started:

• Clone repo
• Create a python virtual environment (python3 -m venv venv) in the root of the repo.
• Open vscode in the repo root (code .)

The provided configuration is very lightweight and should be easily adaptable to other enviroments/setups.
