通过node-red连接mqtt服务端,订阅outTopic主题可以接收到esp8266的消息: ps:在示例中,esp8266视为A端,node-red视为B端,我使用hivemq临时搭建的mqtt服务器视为服务端 ·相同的,通过node-red发布一个主题为“inTopic”的消息: 可以从Serial中看到,esp8266中也收到了由node-red中发
mqttClient.setServer(mqtt_broker, mqtt_port); // 设置MQTT服务器和端口号 String mqttClient_id = "esp8266-" + WiFi.macAddress(); // 根据ESP8266的MAC地址生成客户端ID(避免与其它ESP8266的客户端ID重名) while (!mqttClient.connected()) { Serial.printf("The mqttClient %s connects to the publi...
A DHT 22 sensor is interfaced with the ESP8266 micro-controller to collect sensor data for temperature and humidity, with the raspberry Pi performing functions of MQTT broker to relay sensor data information to a Node-RED dashboard.Paul Macheso...

and the ESP8266MQTTMesh code will change the node's MAC address to match the required pattern. The MAC addresses are based on both the node's chipID as well as the mesh password, ensuring that each node will have a unique MAC address as well as that multiple meshes can run in the sa...
