- 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
