The command header "WizFi250AirCmd:" is case sensitive and has to be sent in this kind. It is 15 Bytes
long.
A <Carriage Return, 0x1d> has to follow the AT command directly.
Air-command header, AT command and Carriage Return should be combined into one packet.
Example usage of the WizFi250AirCmd:
AT+WSET=1,WizFi250_AIRCMD
[OK]
AT+WSEC=1,WPA2,123456789
[OK]
AT+WNET=0,192.168.11.1,255.255.255.0,192.168.11.1
