 The `BluetoothCentralManager` class has several differrent scanning methods:
 
 ```kotlin
-fun scanForPeripherals()
-fun scanForPeripheralsWithServices(serviceUUIDs: Array<UUID>)
-fun scanForPeripheralsWithNames(peripheralNames: Array<String>)
-fun scanForPeripheralsWithAddresses(peripheralAddresses: Array<String>)

+fun scanForPeripherals(resultCallback: (BluetoothPeripheral, ScanResult) -> Unit, scanError: (ScanFailure) -> Unit )
+fun scanForPeripheralsWithServices(serviceUUIDs: Array<UUID>, resultCallback: (BluetoothPeripheral, ScanResult) -> Unit, scanError: (ScanFailure) -> Unit)
+fun scanForPeripheralsWithNames(peripheralNames: Array<String>, resultCallback: (BluetoothPeripheral, ScanResult) -> Unit,  scanError: (ScanFailure) -> Unit)
+fun scanForPeripheralsWithAddresses(peripheralAddresses: Array<String>, resultCallback: (BluetoothPeripheral, ScanResult) -> Unit, scanError: (ScanFailure) -> Unit)
+fun scanForPeripheralsUsingFilters(filters: List<ScanFilter>,resultCallback: (BluetoothPeripheral, ScanResult) -> Unit, scanError: (ScanFailure) -> Unit)
 ```
 
 They all work in the same way and take an array of either service UUIDs, peripheral names or mac addresses. When a peripheral is found your callback lambda will be called with the `BluetoothPeripheral` object and a `ScanResult` object that contains the scan details. The method `scanForPeripheralsUsingFilters` is for scanning using your own list of filters. See [Android documentation](https://developer.android.com/reference/android/bluetooth/le/ScanFilter) for more info on the use of `ScanFilter`.

 The scanning functions are not suspending functions and simply use a lambda function to receive the results.
