Wake-On-LAN Library for ( ESP8266 & ESP32 ), Provide an easy way to send/generate magic packet for any MAC Address. Moreover, support SecureOn feature in some motherboard vendors. Finally, support using custom port number than the default one which is port 9.

This library could be used in other environments. Although, (IPAddress, WiFiUDP, delay()) classes should be available.

Install

To install the library to Arduino IDE by downloading this repository as zip file and navigate to Sketch -> Include library -> Add .ZIP library. Alternatively, navigate to Tools -> Library Manager and search for this library name

To install the library to PlatformIO IDE go to and add the repository link to lib_deps variable OR add the library name lib_deps = https://github.com/a7md0/WakeOnLan.git Or lib_deps = WakeOnLan

Include and initialize WiFiUDP

#include <WiFiUdp.h>
WiFiUDP UDP;

Include and initialize WakeOnLan class

#include <WakeOnLan.h>
WakeOnLan WOL(UDP); // Pass WiFiUDP class

Add this line in void setup() (Optinal)

WOL.setRepeat(3, 100); // Repeat the packet three times with 100ms delay between

Calculate and set the broadcast address, after connecting to WiFi successfully (Optinal)

WOL.calculateBroadcastAddress(WiFi.localIP(), WiFi.subnetMask());

Set the broadcast address manually (Optinal)

WOL.setBroadcastAddress("192.168.1.255");

Usage

Send WOL from char array MAC Address

Set MAC address in variable

const char *MACAddress = "01:23:45:67:89:AB";

Send WOL UDP packet (By default port 9)

WOL.sendMagicPacket(MACAddress);

Send WOL UDP packet (Use port 7)

WOL.sendMagicPacket(MACAddress, 7);

Set MAC address and SecureOn in variable

const char *MACAddress = "01:23:45:67:89:AB";
const char *secureOn = "FE:DC:BA:98:76:54";

Send WOL UDP packet with password (By default port 9)

WOL.sendSecureMagicPacket(MACAddress, secureOn);

Send WOL UDP packet with password (Use port 7)

WOL.sendSecureMagicPacket(MACAddress, secureOn, 7);

Send WOL from byte array MAC Address

Set MAC address in variable

uint8_t MAC[6] = {0x01, 0x23, 0x45, 0x67, 0x89, 0xAB}; // 01:23:45:67:89:AB

Send WOL UDP packet (By default port 9)

WOL.sendMagicPacket(MAC, sizeof(MAC));

Send WOL UDP packet (Use port 7)

WOL.sendMagicPacket(MAC, sizeof(MAC), 7);

Set MAC address and SecureOn in variable

uint8_t MAC[6] = {0x01, 0x23, 0x45, 0x67, 0x89, 0xAB}; // 01:23:45:67:89:AB
uint8_t SECURE_ON[6] = {0xFE, 0xDC, 0xBA, 0x98, 0x76, 0x54}; // FE:DC:BA:98:76:54

Send WOL UDP packet with password (By default port 9)

WOL.sendSecureMagicPacket(MAC, sizeof(MAC), SECURE_ON, sizeof(SECURE_ON));

Send WOL UDP packet with password (Use port 7)

WOL.sendSecureMagicPacket(MAC, sizeof(MAC), SECURE_ON, sizeof(SECURE_ON), 7);

Generate WOL packet

Generate

size_t magicPacketSize = 6 + (6 * 16);  // FF*6 + MAC*16
uint8_t* magicPacket = new uint8_t[magicPacketSize]; // Magic packet will be stored in this variable

uint8_t MAC[6] = {0x01, 0x23, 0x45, 0x67, 0x89, 0xAB}; // 01:23:45:67:89:AB

WOL.generateMagicPacket(magicPacket, magicPacketSize, pMacAddress, sizeof(MAC));

Generate with secure on

size_t magicPacketSize = 6 + (6 * 16) + 6;  // FF*6 + MAC*16 + SecureOn
uint8_t* magicPacket = new uint8_t[magicPacketSize]; // Magic packet will be stored in this variable

uint8_t MAC[6] = {0x01, 0x23, 0x45, 0x67, 0x89, 0xAB}; // MAC Address = 01:23:45:67:89:AB
uint8_t SECURE_ON[6] = {0xFE, 0xDC, 0xBA, 0x98, 0x76, 0x54}; // SecureOn = FE:DC:BA:98:76:54

WOL.generateMagicPacket(magicPacket, magicPacketSize, MAC, sizeof(MAC), SECURE_ON, sizeof(SECURE_ON));
