备注:publishMqttZclCommand方法好像会产生内存泄露问题,特别是在OTA的时候,需要向mqtt大量上报OTA状态的时候。每次调用会泄露52字节;因为mqtt是采用esp32自己的api;不是使用芯科的插件,所以可能导致某些资源(例如json对象)没有释放;暂时的解决办法是直接返回,好像功能也正常,相当奇怪;后面再仔细研究。 这个方法的调用链...
5 mqtt_user = "soundsensor" 6 mqtt_password = "Zap!Pow!Bam!Kapow!" Coming back to the function that we have created to read the noise sensor, we can now initialize an MQTT client after connecting to the WiFi (use mqtt::client::{EspMqttClient, MqttClientConfiguration, QoS},): 1 let...
There are many public MQTT brokers available that can be used for testing and development, but for production use, it’s recommended to set up a private MQTT broker. There is an ESP32 library for MQTT protocol which is called “ PubSubClient”. That can be used to connect to MQTT ...
