The ESP32 can scan for WiFi networks within its range and return the found networks’ SSIDs and signal strength for each network. You’ll find a sample code example in Arduino IDE for ESP32 WiFi Scanner. Open File > Examples > WiFi > WiFiScan sketch. ...
Hi, I made a WiFi scan sample based on the ESP32 IDF. For those who want to see it's open source on GitHub. https://github.com/VALERE91/ESP32_WifiScanarao23 Posts: 30 Joined: Tue Dec 13, 2016 4:44 pm Re: Full Wifi scan sample...

在使用esp32-wifi-manager的典型应用程序中,大多数情况下可以忽略其他消息。 事件参数 回调签名包括一个void*指针。对于大多数事件,此附加参数为空,并作为NULL值发送。一些选择事件具有用户代码可以利用的附加数据。它们如下所示: WM_EVENT_SCAN_DONE与wifi_event_sta_scan_done_t*对象一起发送。 WM_EVENT_STA_...

ESP32的example有完整的SmartConfig demo，可以直接创建项目使用。1. 流程分析 配网主要执行以下流程：（1）初始化网络接口并为应用程序创建事件组。ESP_ERROR_CHECK(esp_netif_init()); s_wifi_event_group = xEventGroupCreate(); ESP_ERROR_CHECK(esp_event_loop_create_default());（2）注册事件处理...
Yes, this clears out any previous connection to WiFi, then re-connects from 0 using WiFi.begin(). I use the disconnect function along with autoConnect and autoReconnect on ESP8266 and it works fine. The scanNetworks() example provided by WiFiscan.ino only has a disconnect() but the issue...
