format
For WEP encryption,the difference between HEX and ASCII formats is the
display format of key, such as WEP64 encryption, its key can be 5 ASCII
characters (such as 12345) or 10 hexadecimal numbers (such as 3132333435).
For WPA/WPA2-PSK encryption,HEX and ASCII formats indicate different
meanings,
HEX format: PMK
ASCII format: PSK

Tips
In WPA/WPA2-PSK (TKIP/CCMP) encryption mode,as the key format is
ASCII, the module must first do the conversion to the key of ASCII format when
it’s power-on, this process increases about 10 seconds to the starting time.And
