While working on IoT projects I mostly use NodeMCU ESP8266 firmware for IoT Implementation. For coding, I use Arduino IDE in which for connectivity with wifi router we define hardcoded variable to write wifi SSID and password that works perfectly fine. But when I use some other wifi that has a different SSID and password we need to change it by coding. Can someone tell me how to get rid of this issue to define SSID and password through coding? Looking for some way through which we can connect to any wifi router by configuration to assign SSID and password through android mobile.
Thanks

I was thinking that there are ways of to find the nearest Access Point to the ESP8266 with some AT commands. Then you can use Strings to save the names of these in an array. With peripherals as buttons or even by serial communication with the PC, maybe you can introduce the information of SSID and to find it in the array of Access Point, if you do it, introduce also the Password, and then try to connect.
I'm not so sure cause I haven't done a code of this before, but maybe this is a solution to connect in a dynamic way to different Access Point.
I hope my humble idea is helpful to you.
