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
