Each [[#ScanFilterFlag|Flag]] bit when set enables using the corresponding ScanFilter data. This is usually a compare with the ScanFilter data and the internal [[#NetworkInfo|NetworkInfo]] data. | |||
* NetworkType: (ScanFilter_NetworkType & NetworkInfo_NetworkType) must be non-zero. | |||
* Ssid: The length fields must match, then memcmp is used. | |||
The filtering func also handles validating the Band/Channel, however these fields are internal only and are not exposed in the user ScanFilter. | |||
