首先明白,本实例的核心部分就是 MQTT 的通信,所以整体的框架是基于 MQTT 的Demo 进行修改, 在以此为基本框架的基础上增加我们需要的组件,功能,函数。 1.1 配网添加(Smart_config ) 删除MQTT Demo中关于配网的操作,使用 Smart_config 配网方式,直接拷贝 Smart_config Demo中的函数: 在这里插入图片描述 Smart_Config...

On the server I have created certificates with Let's Encrypt and with MQTT Explorer everything works correctly in TLS without loading the CA. How can I now get this server to work with my ESP32? I have tried putting only: Code: Select all .address = { .hostname = _endpoint.c_str...
At the very least, you need the hostname or IP address of your MQTT broker. Copy the user name and password that we created previously: 1 [mosquitto-bzzz] 2 wifi_ssid = "ThisAintEither" 3 wifi_password = "NorIsThisMyPassword" 4 mqtt_host = "mqttsystem" 5 mqtt_user = "soundsensor...
