I have followed all the instructions provided on http://allaboutee.com/2015/01/20/esp8266-android-application-for-arduino-pin-control/
I have got the correct setup, I have got the message "Server Ready" in the serial monitor, i have an app similar to this, means the only thing i have done different from the web page is removing two buttons from the app.
But then also whenever i use my app to send request parameters to arduino it says "connection to 192.168.x.x:xx refused" , when i put the same ip and port in chrome, it says Server not reachable, the website may be down, What to do ? , Please help...
