# WPA2 key hex format

## Question

Asked by Coccoliso on 2015-01-19 in Wireless.

Hello,
I have the following problem.
The AP to which I have to connect with the WizFi250 uses WPA2 AES with a key 32 hex numbers (64 digits) key, in command AT + WSEC modules accepts as hexadecimal key WPA key = 8 ~ 63 (ASCII) or 128 (HEX ).
Since 32 Hex numbers are 64-digit format what I have to pass in the command AT + WSEC ?
I tried to fill it with 0 (zero) before and after unsuccessfully …
Another question is on the network that is hidden, in AT + WSET I have to pass the BSID or just the SSID?
Thank You.

Hello Coccoliso

As you said below, WizFi250 can support only 128-hex-digit(64 byte).

Please refer to the below.

[OK]
AT+WSEC=?
0,30 31 32 33 34 35 36 37 38 39 30 31 32 33 34 35 36 37 38 39 30 31 32 33 34 35 36 37 38 39 30 31 32 33 34 35 36 37 38 39 30 31 32 33 34 35 36 37 38 39 30 31 32 33 34 35 36 37 38 39 30 31 32 33 [/quote]
