ConnectWithWEP only for WiFi Link firmware

Description

In this example is shown how to connect to a WEP encrypted network using the WiFi Link library on the Arduino UNO WiFi.
In paticular the sketch allows to print on Serial Monitor more info e.g. MAC address and IP address of board.

Note:
If you use a 40-bit WEP, you need a key of 10 hexadecimal characters long, instead for 128-bit, you need a string of 26 characters long.


Warning:
Use the Arduino IDE 1.8.x  and import the WiFi Link library using the Library Manager.

WiFi Link library

Circuit

Connect the board to PC.

Code

Modify the below sketch inserting the name and the password of your network and after upload the code using Arduino IDE.


Note:
Make sure that the board uses the WiFi Link firmware.

/*

This example connects to a WEP-encrypted Wifi network.
Then it prints the MAC address of the Wifi module,
the IP address obtained, and other network details.

If you use 40-bit WEP, you need a key that is 10 characters long,
and the characters must be hexadecimal (0-9 or A-F).
e.g. for 40-bit, ABBADEAF01 will work, but ABBADEAF won't work
(too short) and ABBAISDEAF won't work (I and S are not
hexadecimal characters).

For 128-bit, you need a string that is 26 characters long.
D0D0DEADF00DABBADEAFBEADED will work because it's 26 characters,
all in the 0-9, A-F range.

Output

Open the Serial Monitor and check if the board is been connected to your network.
