This Arduino library allows ESP8266 and ESP32 to send LINE Notify message, sticker and images.

The library supported Ethernet in ESP32 using LAN8720, TLK110 and IP101 Ethernet modules and ESP8266 using ENC28J60, W5100 and W5500 Ethernet modules

This library allows you to use external Arduino Clients network interfaces e.g. WiFiClient, EthernetClient and GSMClient.

To use external Client, see the ExternalClient examples.

The flash and SD filesystems supports depend on the devices and third party filesystems libraries installed.

To enable PSRAM in ESP32 module with on-board PSRAM chip, in Arduino IDE

In PlatformIO in VSCode IDE, add the following build_flags in your project's platformio.ini file

build_flags = -DBOARD_HAS_PSRAM -mfix-esp32-psram-cache-issue

*When config the IDE or add the build flags to use PSRAM in the ESP32 dev boards that do not have on-board PSRAM chip, your device will be crashed (reset).

In ESP8266, to use external Heap from 1 Mbit SRAM 23LC1024, choose the MMU option 5, 128K External 23LC1024.

To use external Heap from PSRAM, choose the MMU option 6, 1M External 64 MBit PSRAM.

In PlatformIO, PIO_FRAMEWORK_ARDUINO_MMU_EXTERNAL_128K or PIO_FRAMEWORK_ARDUINO_MMU_EXTERNAL_1024K build flag should be assigned in platformio.ini.

To use SRAM/PSRAM in this library, the macro in file FS_Config.h was set.

#define ESP_LINE_NOTIFY_USE_PSRAM

  #include <ESP_Line_Notify.h>

  /* Define the LineNotifyClient object */
  LineNotifyClient line;


  line.token = "Your Line Notify Access Token";
  line.message = "Hello world";

  //The image to send
  line.image.file.path = "/test.jpg";
  line.image.file.storage_type = LineNotify_Storage_Type_Flash; //or LineNotify_Storage_Type_SD
  line.image.file.name = "test.jpg";

  LineNotiFySendingResult result = lineNotify.send(line);

  if (result.status == LineNotify_Sending_Success)
  {
    Serial.printf("Status: %s\n", "success");
    Serial.printf("Text limit: %d\n", result.quota.text.limit);
    Serial.printf("Text remaining: %d\n", result.quota.text.remaining);
    Serial.printf("Image limit: %d\n", result.quota.image.limit);
    Serial.printf("Image remaining: %d\n", result.quota.image.remaining);
    Serial.printf("Reset: %d\n", result.quota.reset);
  }
  else if (result.status == LineNotify_Sending_Error)
  {
    Serial.printf("Status: %s\n", "error");
    Serial.printf("error code: %d\n", result.error.code);
    Serial.printf("error msg: %s\n", result.error.message.c_str());
  }
