// 连接wifi
void connectWifi()
{// 建立WiFiManager对象WiFiManager wifiManager;// wifiManager.resetSettings();// 自动连接WiFi。以下语句的参数是连接时的WiFi名称wifiManager.autoConnect(AutoConnectAP);Serial.println();Serial.println(WiFi Connected!);Serial.println();
} 所有代码

重新上传程序后打开手机可以看到 名叫 AutoConnectAP 的 wifi 名点击连接就可以给开发板配网wifi信息会自动保存在开发板中以后启动开发板无需重新配网
