WireGuard-ESP32-Arduino

WireGuard Implementation for ESP32 Arduino

This is an implementation of the WireGuard® for ESP32 Arduino.

Almost all of this code is based on the WireGuard Implementation for lwIP, but some potion of the code is adjusted to build with ESP32 Arduino.

How to use

1. Include WireGuard-ESP32.h at the early part of the sketch.

#include 

1. Define the instance of the WireGuard class at module level.

static WireGuard wg;

1. Connect to WiFi AP by using WiFi class.

WiFi.begin(ssid, password);
while( !WiFi.isConnected() ) {
    delay(1000);
}

1. Sync the system time via NTP.

configTime(9 * 60 * 60, 0, "ntp.jst.mfeed.ad.jp", "ntp.nict.jp", "time.google.com");

1. Start the WireGuard interface.

wg.begin(
    local_ip,           // IP address of the local interface
    private_key,        // Private key of the local interface
    endpoint_address,   // Address of the endpoint peer.
    public_key,         // Public key of the endpoint peer.
    endpoint_port);     // Port pf the endpoint peer.

You can see an example sketch uptime_post.ino, which connects SORACOM Arc WireGuard endpoint and post uptime to SORACOM Harvest via WireGuard connection.
