可以通过直接在代码中修改wifi的ssid、password进行连接,也支持通过小程序方式进行配网,通过这种方式的话,程序将会把配置的ssid、password存储到flash中(spiffs方式),下次断电重启后可直接从flash中读取ssid、password实现wifi连接。代码实现如下:#include <WiFi.h> #include <SPIFFS.h> // 定义存储文件的文件名 const ...
每次回答完毕后,会有提示音播放,提示音文件存储在esp32的SPIFFS中,存储方法:连接好esp32,然后依次点击图中指示的位置。 便捷配网功能 网络连接通过读取ESP32 flash的NVS中存储的Wi-Fi信息实现。设备启动后开始联网时,板载LED会闪烁,屏幕显示相应的连接状态信息。esp32处于无网状态时,ESP32启动AP模式,创建临时网络热点...

To play the WAV file you will need to download the file to the SPIFFS file system. This is now annoyingly hard to find on platform.io - watch this video to see how to find it. The pins currently configured are: FunctionGPIO PinNotes ...
