The hard part is to write routines in “rainy-day” scenarios, such as WIFI_EVENT_STA_DISCONNECTED. Generally, it is easy to write code in “sunny-day” scenarios, such as WIFI_EVENT_STA_START and WIFI_EVENT_STA_CONNECTED. Refer to ESP32 Wi-Fi station General Scenario and ESP32 Wi-Fi AP General Scenario. This article also reveals some design details of the Wi-Fi driver. It describes the principles of using the Wi-Fi APIs, the limitations of the current Wi-Fi API implementation, and the most common pitfalls in using Wi-Fi. This article is supplementary to the Wi-Fi APIs/Examples. It is not a MUST, but it is strongly recommended that you take some time to read this article first, especially if you want to program a robust Wi-Fi application. Generally, the most effective way to begin your own Wi-Fi application is to select an example which is similar to your own application, and port the useful part into your project. How To Write a Wi-Fi Application  Preparation  Up to 20 MBit/s TCP throughput and 30 MBit/s UDP throughput over the air
