build

Added in API level 21

public ScanSettings build ()

Build ScanSettings.

Returns
`ScanSettings`

Throws
`IllegalArgumentException`	if the settings cannot be built.

setCallbackType

Added in API level 23

public ScanSettings.Builder setCallbackType (int callbackType)

Set callback type for Bluetooth LE scan.

Parameters
`callbackType`	`int`: The callback type flags for the scan.

Returns
`ScanSettings.Builder`

Throws
`IllegalArgumentException`	If the `callbackType` is invalid.

setLegacy

Added in API level 26

public ScanSettings.Builder setLegacy (boolean legacy)

Set whether only legacy advertisements should be returned in scan results. Legacy advertisements include advertisements as specified by the Bluetooth core specification 4.2 and below. This is true by default for compatibility with older apps.

Parameters
`legacy`	`boolean`: true if only legacy advertisements will be returned

Returns
`ScanSettings.Builder`

setMatchMode

Added in API level 23

public ScanSettings.Builder setMatchMode (int matchMode)

Set match mode for Bluetooth LE scan filters hardware match.

Parameters
`matchMode`	`int`: The match mode can be one of `ScanSettings.MATCH_MODE_AGGRESSIVE` or `ScanSettings.MATCH_MODE_STICKY`

Returns
`ScanSettings.Builder`

Throws
`IllegalArgumentException`	If the `matchMode` is invalid.

setNumOfMatches

Added in API level 23

public ScanSettings.Builder setNumOfMatches (int numOfMatches)

Set the number of matches for Bluetooth LE scan filters hardware match.

Parameters
`numOfMatches`	`int`: The num of matches can be one of `ScanSettings.MATCH_NUM_ONE_ADVERTISEMENT` or `ScanSettings.MATCH_NUM_FEW_ADVERTISEMENT` or `ScanSettings.MATCH_NUM_MAX_ADVERTISEMENT`

Returns
`ScanSettings.Builder`

Throws
`IllegalArgumentException`	If the `matchMode` is invalid.

setPhy

Added in API level 26

public ScanSettings.Builder setPhy (int phy)

Set the Physical Layer to use during this scan. This is used only if setLegacy(boolean) is set to false. BluetoothAdapter.isLeCodedPhySupported() may be used to check whether LE Coded phy is supported by calling BluetoothAdapter.isLeCodedPhySupported(). Selecting an unsupported phy will result in failure to start scan.

Parameters
`phy`	`int`: Can be one of `BluetoothDevice.PHY_LE_1M`, `BluetoothDevice.PHY_LE_CODED` or `ScanSettings.PHY_LE_ALL_SUPPORTED`

Returns
`ScanSettings.Builder`

setReportDelay

Added in API level 21

public ScanSettings.Builder setReportDelay (long reportDelayMillis)

Set report delay timestamp for Bluetooth LE scan. If set to 0, you will be notified of scan results immediately. If > 0, scan results are queued up and delivered after the requested delay or 5000 milliseconds (whichever is higher). Note scan results may be delivered sooner if the internal buffers fill up.

Parameters
`reportDelayMillis`	`long`: how frequently scan results should be delivered in milliseconds

Returns
`ScanSettings.Builder`

Throws
`IllegalArgumentException`	if `reportDelayMillis` < 0

setScanMode

Added in API level 21

public ScanSettings.Builder setScanMode (int scanMode)

Set scan mode for Bluetooth LE scan.

Parameters
`scanMode`	`int`: The scan mode can be one of `ScanSettings.SCAN_MODE_LOW_POWER`, `ScanSettings.SCAN_MODE_BALANCED` or `ScanSettings.SCAN_MODE_LOW_LATENCY`.

Returns
`ScanSettings.Builder`

Throws
`IllegalArgumentException`	If the `scanMode` is invalid.
