2️⃣ ESP32 + Embedded Rust Example

Target: ESP32
Board: ESP32-WROOM

📌 Goal:

• WiFi Communication using esp-wifi
• Energy-efficient idle mode

🛠 Dependencies

[dependencies]
esp-idf-sys = "0.30"
esp-idf-hal = "0.38"
embedded-svc = "0.24"
wifi = "0.1"

⚡ Code: WiFi + Low Power

#![no_std]
#![no_main]

use embedded_svc::wifi::{AccessPointConfiguration, Configuration};
use esp_idf_hal::peripherals::Peripherals;
use esp_idf_sys as _;

#[entry]
fn main() {
    let peripherals = Peripherals::take().unwrap();
    let mut wifi = peripherals.wifi;

    wifi.set_configuration(&Configuration::AccessPoint(
        AccessPointConfiguration {
            ssid: "ESP_Rust".into(),
            password: "password123".into(),
            ..Default::default()
        },
    )).unwrap();

    loop {
        esp_idf_sys::esp_light_sleep_start(); // Low-power sleep mode
    }
}

✅ ESP32 runs a WiFi Access Point
✅ Energy-efficient with light sleep mode
