Is it possible to program EP8266 and variants like ESP01/ NodeMcu/WeMos D1 to provide an interface to enter wifi credentials and save?
Example: Assume that I have a WeMos D1 with my Wifi credentials inside the code. Now if i want to demonstrate at a different place, with different Wifi connection, how can i do it [without uploading code again with new credentials]?
I am looking for dynamic way. Please suggest
