How to manage dynamic WIFI configuration on esp8266 or esp32

One most common need when you use IOT device with WIFI is the first connection attemp, It’s very tedious to hard code WIFI parameter, but a library allows you to connect your esp8266/esp32 to different Access Points (AP) without having to hard code and upload new code to your board. Additionally, you can also add custom parameters (variables) and manage multiple SSID connections with the WiFiManager library.

Network Time Protocol (NTP), Timezone and Daylight saving time (DST) with esp8266, esp32 or Arduino

When you create a device you probably need to know the correct time, on wifi device the resonably choiche is to use Internet to get time via NTP.

FTP server on esp8266 and esp32

For static information (Web pages for examples), that not change frequently, esp8266 or esp32 have internal SPIFFS (SPI Flash File System) and you can upload data via Arduino IDE as explained in the article “WeMos D1 mini (esp8266), integrated SPIFFS Filesystem” but for fast operation and future support It’s usefully use FTP.
