Is there a way to steup wireless ssid and password externally? I mean not from the code like the common way
char ssid[] = "myNetwork"; // your network SSID (name)
char pass[] = "myPassword"; // your network password
status = WiFi.begin(ssid, pass);
Using code method, ESP8266 can only connect to specific router. But I would like to carry ESP8266 to a new environment and let it connect to the wireless network there.
