CC3200 Serial Wifi demo "SOCK ERROR"

Hi,

I am trying to run the The serial WiFi application as per the
procedure mentoined in the below wiki page.

http://processors.wiki.ti.com/index.php/CC32xx_Serial_Wifi

I used the CC3200SDK1.1.0 and programmed "serial_wifi.bin" to
CC3200-LAUNCHXLs with CCS UniFlash v3.2. (run with STA Mode)

When I try to run the connect command "connect cc3200demo 0 0"
through Tera Term I get below error.

>>> [SOCK ERROR] - TX FAILED : socket 0 , reason (-9)

Please let me know if there is any else to be condidered when
running the Serial Wifi demo.

Best Regards
Kummi
