Now, you’re in control. Use any other MQTT client to publish the MQTT message “time” on “topic/qos1.” This will prompt a response from your ESP32 module on the MQTT topic “topic/qos0” and the console log. You’ll see the actual date and time from the ESP32, all at your ...

查找资料发现就是串口通信打印的log而已 ESP32 一共有三个 UART 通讯接口,设备号从 0~2,即 UART0,UART1,UART2。这三个串口的管脚不 是固定的,是可以重映射到任意的 IO 口的。 ESP32 的 BOOT 程序把 UART0 用于程序下载,LOG 输出,实验 hello world 的 LOG 就是从 UART0 输出的。在 BOOT 程序里,把...
