The problem, basically, is that when we use two publish methods in a row, even if we establish different topic names, the MQTT Client is actually sending the following messages to the first topic mentioned only.
if (mqtt_client.connected()) { // Verificando se o cliente está conectado antes de publicar
// Publicar os Topicos no MQTT Broker
mqtt_client.publish(mqtt_topic_arduino_mac, arduino_mac.c_str());
mqtt_client.loop(); // Wait until message is sent
mqtt_client.publish(mqtt_topic_arduino_ip, arduino_ip.c_str());
mqtt_client.loop(); // Wait until message is sent
}
The if statement above, instead of sending a message to topic 1 with message X, and a message to topic 2 with message Y, it is actually sending message to topic 1 with message X and message to topic 1 with message Y.
