安装esp8266驱动/pubsubclient
波特率115200
兄台写的挺好,有代码,改造一下就行了,直接附上地址
#include <ESP8266WiFi.h>
#include <PubSubClient.h>
const char* ssid = "nihen_pc";
const char* password = "****";
const char* mqtt_server = "192.168.137.41";
const int mqttPort = 1883;
WiFiClient espClient;
PubSubClient client(espClient);
void setup() {
Serial.begin(115200);
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.println("Connecting to WiFi..");
}
Serial.println("Connected to the WiFi network");
client.setServer(mqtt_server, mqttPort);
client.setCallback(callback);
while (!client.connected()) {
Serial.println("Connecting to MQTT...");
if (client.connect("ESP8266Client")) {
Serial.println("connected");
} else {
Serial.print("failed with state ");
Serial.print(client.state());
delay(2000);
}
}
client.publish("esp/test", "Hello from ESP8266");
client.subscribe("esp/test");
}
void callback(char* topic, byte* payload, unsigned int length) {
Serial.print("Message arrived in topic: ");
Serial.println(topic);
Serial.print("Message:");
for (int i = 0; i < length; i++) {
Serial.print((char)payload[i]);
}
}
void loop() {
client.loop();
}
用docker部署RabbitMQ,使用mqtt
rabbitmq - docker大法好
默认web端口15672
注意要开启mqtt
客户端用的MqttBox
