Aunque se reciben todos los mensajes en el radio, se requiere discriminar los mensajes que son dirigidos hacia el dispositivo local.<\/p>\n

Se modifica las intrucciones de recepci\u00f3n a\u00f1adiendo un bloque para discriminar si el mensaje es para el dispositivo local. Esto implica descomponer la trama enviada en sus partes y convertir al tipo de dato a usar.<\/p>\n

Las operaciones se realizan por caracter o byte con el objetivo de establecer el mecanismo a usar cuando se usa LoRaWan<\/p>\n
