This library enables sending messages through the LINE Messaging API using ESP32. It's designed to be compatible with the SPRESENSE_ESP8266_LINE_Messaging_API library while utilizing ESP32's native WiFi capabilities.

1. Download this library and save it as a ZIP file
2. Open Arduino IDE, go to "Sketch" → "Include Library" → "Add .ZIP Library..."
3. Select the downloaded ZIP file to install

#include "ESP32LineMessenger.h"

// WiFi and LINE configuration
const char* ssid = "your_wifi_ssid";
const char* password = "your_wifi_password";
const char* accessToken = "your_line_access_token";

// Create library instance
ESP32LineMessenger line;

void setup() {
  Serial.begin(115200);
  
  // Set access token
  line.setAccessToken(accessToken);
  
  // Connect to WiFi
  if (line.connectWiFi(ssid, password, true)) {
    // Send message
    line.sendMessage("Hello from ESP32!", true);
  }
}

void loop() {
  // Additional code if needed
}

ESP32LineMessenger();  // Basic constructor
ESP32LineMessenger(const char* token);  // Constructor with access token

void setAccessToken(const char* token);

bool connectWiFi(const char* ssid, const char* password, bool showConnect = true);

• ssid: WiFi SSID
• password: WiFi password
• showConnect: Whether to show connection status on serial (default: true)
• Returns: true on success, false on failure

bool sendMessage(const char* message, bool showSend = true);

• message: Message to send
• showSend: Whether to show send status on serial (default: true)
• Returns: true on success, false on failure

bool isWiFiConnected();  // Check WiFi connection status
void setDebug(bool debug);  // Enable/disable debug mode

1. Go to LINE Developers
2. Create a new provider
3. Create a Messaging API channel
4. Issue a long-lived channel access token
5. Set the token in your program

• ESP32_LINE_Basic: Basic usage example
• ESP32_LINE_Advanced: Example with scheduled messages and button-triggered sending

• This library is specifically designed for ESP32
• SSL certificate verification is disabled (recommended to use proper certificates in production)
• Usage of LINE Messaging API is subject to LINE's Terms of Use

• Class name changed from LineMessenger to ESP32LineMessenger
• Uses ESP32's native WiFi library instead of ESP8266's AT commands
• Added features like WiFi connection status check and debug mode

• If WiFi connection fails, verify SSID and password
• If message sending fails, check the validity of your access token
• Enable debug mode for detailed error information
