ZMQ Demo

A demonstration project showcasing client-server communication using ZeroMQ (ZMQ) with Protocol Buffers for message serialization. The project implements a request-response pattern where a Python client sends random messages to a Rust server.

Overview

The system consists of two main components:

• A Python client that generates and sends random messages
• A Rust server (executed on a Raspberry Pi) that receives messages and responds with acknowledgments

Getting Started

Prerequisites

• A Raspberry Pi on Ubuntu 20.04+, accessible from SSH
• Python 3.8+

Setup

cd zmq_demo
python -m venv venv
source venv/bin/activate
pip install -r requirements.txt
./generate_protobuf.sh
docker build -t zmq_demo .
docker run -it -v $(pwd):/workspace zmq_demo
cd /workspace/server
cargo build

Deploy the Server

Deploy the target/armv7-unknown-linux-gnueabihf/debug/rasp0mq binary on the target through SSH. You can update the bash variables TARGET_SSH and TARGET_DIR in the script deploy.sh, then execute it:

cargo run

Test

cd zmq_demo/client/src
python3 zmq_client.py --id 42
