Rust HTTPS Client for the ESP32-C3 chip

Tested on the Rust ESP Board.

On run, it automatically builds the firmware, flashes the connected board and monitors its console. You may customize this behaviour in the .cargo/config.toml file.

Run in Windows PowerShell:

$env:SSID="your_wifi_ssid"; $env:PASSWORD="your_wifi_password"; cargo run --release; $env:SSID=$null; $env:PASSWORD=$null;

Run in Linux:

SSID="your_wifi_ssid" PASSWORD="your_wifi_password" cargo run --release

Note: If you try running it without the --release flag you will get errors related to no free memory for allocation in the TLS connect.

Logic

1. Initializes the controller and enables the ESP wi-fi client.
2. Initializes Embassy tasks and executor.
3. Connects to your access point using the specified your_wifi_ssid and your_wifi_password
4. Gets an IP address from the DHCP server in your network.
5. Connects via HTTPS to the www.google.com website, checks its certificate using the stored PEM file in .src/certs/www.google.com.pem, and establishes an encrypted connection.
6. Tries to GET www.google.com/notfound page.
7. Receives result from the server and prints it to the console.
