Hai !

I am having two wifi modules and I have configured the initial settings.

In both the modules I am getting the status ''Handshake Complete''.

After this i tried to give command ''AT'' and both giving the response OK

now I have sent the command ''AT+S.SOCKD=8855'' only one module responds OK and the other now is showing ''ERROR: Command not found''. 

Could you please help me why it is so?

Also tell me how to update the firmware through cable

    Hi,

    ''command not found'' means the module contains an old FW version (use FW3.5 on both of them), or provided command was not properly formatted (check string).

    About the UART update, take a look at the hands-on manual.
