My name is Elisavet and I am new here.

I bought a ESP8266 module in order my Arduino board support wireless connectivity.

I have a question about it:
Is there any way to connect my Arduino/ESP8266 board to my Laptop and every time I change network, I want be able to set different SSID and password for my network. Until know I have observe in websites that I have to set the SSID and password in programming phase. But I dont want that. I want to change the network configuration with another way. Is that possible?

I gave up using the AT Commands. In my oppinion they are not good to be used with arduino at least to make a web server.
Now I'm using the ESP8266 as arduino board itself as it has a lot more memory, it is faster and you can get rid of AT commands. More info here https://github.com/esp8266/Arduino

On that approach I made the ESP8266 set a softAP with a captive portal. You connecto to it (direcly vía wifi) and a web page appears to allow you to setup your WLAN. Then you connect back to your WLAN and the ESP8266 will be there too. I posted it as example here https://github.com/esp8266/Arduino/tree ... alAdvanced

I insist this is all about running arduino sketches INSIDE the ESP8266.

How can I program the ESP8266? I think, it needs a 3V breakout board in order to connect it to computer. I have only a 5V breakout board. Can I change it somehow, in order to program the ESP8266?

I saw these files: https://github.com/esp8266/Arduino/tree ... alAdvanced

Which of these files I should upload to the ESP8266? Can I upload multiple files? (newbie questions )

Hi, I compiled the "CaptivePortalAdvanced" but it shows me some errors.
Have you done any changes in the code?

The Error is - > 'ESP8266WiFi' was not declared in this scope
