• Description:
Another fantastic feature of WiFi-capable microcontrollers is the ability to either connect to a wireless network (Station mode) or creating their own (Access Point mode). In a previous video (youtu.be/uFjWKhScnVY) we saw how both modes work.
In this tutorial I show how to build an application that switches between the two. I give the user the option—via a web interface— of inputting her or his Wi-Fi credentials, storing them in flash memory (using the SPI Flash File System), and using them to access a network.
If no Wi-Fi credentials are given, or if the network is not available, the ESP8266 creates its own that we can access to enter the web interface.
