```
public abstract class DfuBaseService
extends android.app.IntentService
```
The DFU Service provides full support for Over-the-Air (OTA) Device Firmware Update (DFU) by Nordic Semiconductor. With the Soft Device 7.0.0+ it allows to upload a new Soft Device, new Bootloader and a new Application. For older soft devices only the Application update is supported.
To run the service to your application extend it in your project and overwrite the missing method. Remember to add your class to the AndroidManifest.xml file.

The DfuServiceInitiator object should be used to start the DFU Service.
```
 final DfuServiceInitiator starter = new DfuServiceInitiator(mSelectedDevice.getAddress())
                .setDeviceName(mSelectedDevice.getName())
                .setKeepBond(keepBond)
                .setZip(mFileStreamUri, mFilePath)
                .start(this, DfuService.class);
 
```
You may register the progress and log listeners using the DfuServiceListenerHelper helper class. See DfuProgressListener and DfuLogListener for more information.

The service will show its progress on the notification bar and will send local broadcasts to the application.

  - EXTRA_RESTORE_BOND
```
public static final java.lang.String EXTRA_RESTORE_BOND
```
    If the new firmware (application) does not share the bond information with the old one, the bond information is lost. Set this flag to true to make the service create new bond with the new application when the upload is done (and remove the old one). When set to false (default), the DFU service assumes that the LTK is shared between them. Note: currently it is not possible to remove the old bond without creating a new one so if your old application supported bonding while the new one does not you have to modify the source code yourself.
    
    In case of updating the soft device the application is always removed together with the bond information.
    
    Search for occurrences of EXTRA_RESTORE_BOND in this file to check the implementation and get more details.
    
    See Also:
    
    Constant Field Values
  - EXTRA_KEEP_BOND
```
public static final java.lang.String EXTRA_KEEP_BOND
```
    This flag indicated whether the bond information should be kept or removed after an upgrade of the Application. If an application is being updated on a bonded device with the DFU Bootloader that has been configured to preserve the bond information for the new application, set it to true.
    
    By default the Legacy DFU Bootloader clears the whole application's memory. It may be however configured in the \Nordic\nrf51\components\libraries\bootloader_dfu\dfu_types.h file (sdk 11, line 76: #define DFU_APP_DATA_RESERVED 0x0000) to preserve some pages. The BLE_APP_HRM_DFU sample app stores the LTK and System Attributes in the first two pages, so in order to preserve the bond information this value should be changed to 0x0800 or more. For Secure DFU this value is by default set to 3 pages. When those data are preserved, the new Application will notify the app with the Service Changed indication when launched for the first time. Otherwise this service will remove the bond information from the phone and force to refresh the device cache (see refreshDeviceCache(android.bluetooth.BluetoothGatt, boolean)).
    
    In contrast to EXTRA_RESTORE_BOND this flag will not remove the old bonding and recreate a new one, but will keep the bond information untouched.
    
    The default value of this flag is false
    
    See Also:
    
    Constant Field Values
  - EXTRA_FORCE_DFU
```
public static final java.lang.String EXTRA_FORCE_DFU
```
    This property must contain a boolean value.
    The DfuBaseService, when connected to a DFU target will check whether it is in application or in DFU bootloader mode. For DFU implementations from SDK 7.0 or newer this is done by reading the value of DFU Version characteristic. If the returned value is equal to 0x0100 (major = 0, minor = 1) it means that we are in the application mode and jump to the bootloader mode is required.
    However, for DFU implementations from older SDKs, where there was no DFU Version characteristic, the service must guess. If this option is set to false (default) it will count number of device's services. If the count is equal to 3 (Generic Access, Generic Attribute, DFU Service) it will assume that it's in DFU mode. If greater than 3 - in app mode. This guessing may not be always correct. One situation may be when the nRF chip is used to flash update on external MCU using DFU. The DFU procedure may be implemented in the application, which may (and usually does) have more services. In such case set the value of this property to true.

    Constant Field Values
  - EXTRA_UNSAFE_EXPERIMENTAL_BUTTONLESS_DFU
```
public static final java.lang.String EXTRA_UNSAFE_EXPERIMENTAL_BUTTONLESS_DFU
```
    Set this flag to true to enable experimental buttonless feature in Secure DFU. When the experimental Buttonless DFU Service is found on a device, the service will use it to switch the device to the bootloader mode, connect to it in that mode and proceed with DFU.
    Please, read the information below before setting it to true.
    In the SDK 12.x the Buttonless DFU feature for Secure DFU was experimental. It is NOT recommended to use it: it was not properly tested, had implementation bugs (e.g. https://devzone.nordicsemi.com/question/100609/sdk-12-bootloader-erased-after-programming/) and does not required encryption and therefore may lead to DOS attack (anyone can use it to switch the device to bootloader mode). However, as there is no other way to trigger bootloader mode on devices without a button, this DFU Library supports this service, but the feature must be explicitly enabled here. Be aware, that setting this flag to false will no protect your devices from this kind of attacks, as an attacker may use another app for that purpose. To be sure your device is secure remove this experimental service from your device.
    Spec:
    Buttonless DFU Service UUID: 8E400001-F315-4F60-9FB8-838830DAEA50
    Buttonless DFU characteristic UUID: 8E400001-F315-4F60-9FB8-838830DAEA50 (the same)
    Enter Bootloader Op Code: 0x01
    Correct return value: 0x20-01-01 , where:
    0x20 - Response Op Code
    0x01 - Request Code
    0x01 - Success
    The device should disconnect and restart in DFU mode after sending the notification.
    In SDK 13 this issue will be fixed by a proper implementation (bonding required, passing bond information to the bootloader, encryption, well tested). It is recommended to use this new service when SDK 13 (or later) is out. TODO: fix the docs when SDK 13 is out.

  - EXTRA_PACKET_RECEIPT_NOTIFICATIONS_ENABLED
```
public static final java.lang.String EXTRA_PACKET_RECEIPT_NOTIFICATIONS_ENABLED
```
    This property must contain a boolean value.
    If true the Packet Receipt Notification procedure will be enabled. See DFU documentation on http://infocenter.nordicsemi.com for more details. The number of packets before receiving a Packet Receipt Notification is set with property EXTRA_PACKET_RECEIPT_NOTIFICATIONS_VALUE. The PRNs by default are enabled on devices running Android 4.3, 4.4.x and 5.x and disabled on 6.x and newer.
    
    See Also:
    
    EXTRA_PACKET_RECEIPT_NOTIFICATIONS_VALUE, Constant Field Values
  - EXTRA_PACKET_RECEIPT_NOTIFICATIONS_VALUE
```
public static final java.lang.String EXTRA_PACKET_RECEIPT_NOTIFICATIONS_VALUE
```
    This property must contain a positive integer value, usually from range 1-200.
    The default value is . Setting it to 0 will disable the Packet Receipt Notification procedure. When sending a firmware using the DFU procedure the service will send this number of packets before waiting for a notification. Packet Receipt Notifications are used to synchronize the sender with receiver.
    On Android, calling BluetoothGatt.writeCharacteristic(BluetoothGattCharacteristic) simply adds the packet to outgoing queue before returning the callback. Adding the next packet in the callback is much faster than the real transmission (also the speed depends on the device chip manufacturer) and the queue may reach its limit. When does, the transmission stops and Android Bluetooth hangs (see Note below). Using PRN procedure eliminates this problem as the notification is send when all packets were delivered the queue is empty.
    Note: this bug has been fixed on Android 6.0 Marshmallow and now no notifications are required. The onCharacteristicWrite callback will be postponed until half of the queue is empty and upload will be resumed automatically. Disabling PRNs speeds up the upload process on those devices.

A ZIP distribution packet may be created using the 'nrf utility' command line application, that is a part of Master Control Panel 3.8.0.The ZIP file MAY contain only the following files: softdevice.hex/bin, bootloader.hex/bin, application.hex/bin to determine the type based on its name. At lease one of them MUST be present.
    If this parameter is not provided the type is assumed as follows:
    1. If the EXTRA_FILE_MIME_TYPE field is null or is equal to "application/octet-stream" - the TYPE_APPLICATION is assumed.
    2. If the EXTRA_FILE_MIME_TYPE field is equal to "application/zip" - the TYPE_AUTO is assumed.

```
public static final int TYPE_AUTO
```
    A ZIP file that consists of more than 1 file. Since SDK 8.0 the ZIP Distribution packet is a recommended way of delivering firmware files. Please, see the DFU documentation for more details. A ZIP distribution packet may be created using the 'nrf utility' command line application, that is a part of Master Control Panel 3.8.0. For backwards compatibility this library supports also ZIP files without the manifest file. Instead they must follow the fixed naming convention: The names of files in the ZIP must be: softdevice.hex (or .bin), bootloader.hex (or .bin), application.hex (or .bin) in order to be read correctly. Using the Soft Device v7.0.0+ the Soft Device and Bootloader may be updated and sent together. In case of additional application file included, the service will try to send Soft Device, Bootloader and Application together (which is not supported currently) and if it fails, send first SD+BL, reconnect and send the application in the following connection.
    
    Since the DFU Library 0.5 you may specify the Init packet, that will be send prior to the firmware. The init packet contains some verification data, like a device type and revision, application version or a list of supported Soft Devices. The Init packet is required if Extended Init Packet is used by the DFU bootloader (SDK 7.0+). In case of using the compatibility ZIP files the Init packet for the Soft Device and Bootloader must be in the 'system.dat' file while for the application in the 'application.dat' file (included in the ZIP). The CRC in the 'system.dat' must be a CRC of both BIN contents if both a Soft Device and a Bootloader is present.

The activity will be launched when user click the notification. DfuService will add Intent.FLAG_ACTIVITY_NEW_TASK flag and the following extras:
    - EXTRA_DEVICE_ADDRESS - target device address
    - EXTRA_DEVICE_NAME - target device name
    - EXTRA_PROGRESS - the connection state (values < 0)*, current progress (0-100) or error number if ERROR_MASK bit set.
    If your application disabled DFU notifications by calling DfuServiceInitiator.setDisableNotification(boolean) with parameter true this method will never be called and may return null.
