也可以直接通过github下载源码,放到你的Arduino libraries文件夹(深入学习者,可以查看源码然后改造源码,达到自定义配网功能) 2.4 WiFiManager工作原理 1、当你的ESP8266上电启动时,它首先进入STA模式,然后尝试去连接之前已经保存过的AP热点(如果你不了解STA和AP的区别,麻烦参考ESP8266开发之旅 网络篇③ Soft-AP——ESP...
You can wake up the ESP32 from deep sleep using the touch pins. This section shows how to do that using the Arduino IDE. Enable Touch Wake-Up Enabling the ESP32 to wake up using a touchpin is simple. In the Arduino IDE, you need to use the following function—pass as argument the...
