/*
This example shows how to use the All Channel Scan or Fast Scan to connect
to a Wi-Fi network.
In the Fast Scan mode, the scan will stop as soon as the first network matching
the SSID is found. In this mode, an application can set threshold for the
authentication mode and the Signal strength. Networks that do not meet the
threshold requirements will be ignored.
In the All Channel Scan mode, the scan will end only after all the channels
are scanned, and connection will start with the best network. The networks
can be sorted based on Authentication Mode or Signal Strength. The priority
for the Authentication mode is: WPA2 > WPA > WEP > Open
