Parameters

band: WifiBand

one of the following band constants defined in WifiScanner#WIFI_BAND_* constants. 1. WifiScanner#WIFI_BAND_UNSPECIFIED=0 - no band specified; Looks for the channels in all the available bands - 2.4 GHz, 5 GHz, 6 GHz and 60 GHz 2. WifiScanner#WIFI_BAND_24_GHZ=1 3. WifiScanner#WIFI_BAND_5_GHZ_WITH_DFS=6 4. WifiScanner#WIFI_BAND_BOTH_WITH_DFS=7 5. WifiScanner#WIFI_BAND_6_GHZ=8 6. WifiScanner#WIFI_BAND_24_5_WITH_DFS_6_GHZ=15 7. WifiScanner#WIFI_BAND_60_GHZ=16 8. WifiScanner#WIFI_BAND_24_5_WITH_DFS_6_60_GHZ=31

mode: WifiAvailableChannelModes

Bitwise OR of WifiAvailableChannel#OP_MODE_* constants e.g. WifiAvailableChannel#OP_MODE_WIFI_AWARE

Returns

IList<WifiAvailableChannel>

a list of WifiAvailableChannel

Attributes: RegisterAttribute RequiresPermissionAttribute

Remarks

Note: the band parameter which is specified as a WifiScanner#WIFI_BAND_* constant is limited to one of the band values specified below. Specifically, if the 5GHz band is included then it must include the DFS channels - an exception will be thrown otherwise. The caller should not make any assumptions about whether DFS channels are allowed. This API will indicate whether DFS channels are allowed for the specified operation mode(s) per device policy.
