http request timeout problem

[bluedays000]

I am working with Arduino Uno and ESP8266.

I connected ESP8266 with Arduino Uno, and downloaded this library. (https://github.com/Diaoul/arduino-ESP8266)..

'joinAP' was OK and 'connect' was also OK.

But the problem was http request.

"getStatus(wifi.send("GET / HTTP/1.0\r\n\r\n"))" in setup code always showed me 'TIMEOUT'.

I just changed SSID, PASS, DSP_IP and port number.. but it doesn't work well.. T.T

Below is my code.

Please save my code..

}
