OTAA_LED.ino

/*
 * HelTec Automation(TM) LoRaWAN 1.0.2 OTAA example use OTAA, CLASS A
 *
 * Function summary:
 *
 * - You can use port 4 to control the LED light.
 *
 * - If the issued value is 1(ASCII), the lamp will be lit.
 *
 * - The release value is 2(ASCII) and the light will be turned off.
 *
 * - use internal RTC(150KHz);
 *
 * - Include stop mode and deep sleep mode;
 *
 * - 15S data send cycle;
 *
 * - Informations output via serial(115200);
 *
 * - Only ESP32 + LoRa series boards can use this library, need a license
 *   to make the code run(check you license here: http://www.heltec.cn/search/);
 *
 * You can change some definition in "Commissioning.h" and "LoRaMac-definitions.h"
