We are fairly new to ESP8266 and Arduino. We can create an AP, but everytime we switch the ESP8266 off, all the settings related to the AP are no longer there. How can we make sure that we can save and access the SSID and PASSWORD after we restart the ESP8266 (without any connection to the computer) ? This is the code we are working on.
Please help us figure this out. Thank you!
