Method of setting TCP Client and exchanging data in Data Mode

Socket Open
This section explains how to open <TCP Client Socket> and communicate with peer system. Below is an
example showing how to set TCP Client and change the mode to data mode. It also explains parameters of
<AT+SCON> command.
(AT+SCON=<OpenType>,<SocketType>,<RemoteIP>,<RemotePort>,<LocalPort>,<DataMode>)
If you enter <O> or <SO> value to <Open Type> parameter, WizFi250 will try to connect to TCP Server
immediately. But when using <S> value, WizFi250 will try to connect to TCP Server after reboot and you have to
set <SocketType>,<RemoteIP>,<RemotePort> and <LocalPort> as below
In order to set WizFi250 to data mode, you have to enter 1 value to <Data Mode> parameter of <AT+SCON>
command. For detailed information to this command, refer to AT+SCON.
