esp8266_e22_06_WakeUpFromWOR.ino

/*
 * EBYTE LoRa E22
 * Stay in sleep mode and wait a wake up WOR message
 *
 * You must configure the address with 0 3 23 with WOR receiver enable
 * and pay attention that WOR period must be the same of sender
 *
 * Pai attention e22 support RSSI, if you want use that functionality you must enable RSSI on configuration
 * configuration.TRANSMISSION_MODE.enableRSSI = RSSI_ENABLED;
 *
 * and uncomment #define ENABLE_RSSI true in this sketch
