Example project for using iroh on an ESP32

This repository contains two completely separate Rust projects (no Cargo workspace):

• server/ — ESP32 endpoint project (using custom iroh branch)
• client/ — Desktop test client (published crates.io iroh)

Each directory has its own Cargo.toml and lockfile.

Build / run

Server (ESP32)

An ESP32 device must be connected over USB-C when running the server. You need an ESP32 with SPIRAM to run this example, e.g. an ESP32-WROVER that is frequently included in ESP32 dev kits.

cd server
WIFI_CONFIG='SSID:PASSWORD' cargo run --release

Client

cd client
cargo run <endpoint-ticket>

Use a long ticket (with IP address) for direct dialing.
