Prop	Type
message	string

DfuUpdateOptions

Specifies the options required for initiating the DFU process.

Prop	Type	Description	Since
deviceAddress	string	The target device address. On Android this is the BLE MAC address. On iOS and web it is a randomly generated UUID identifier.	1.0.0
deviceName	string	The name of the device	1.0.0
filePath	string	The path to the firmware file	1.0.0
dfuOptions	DfuOptions	The additional options for the DFU process	1.0.0

DfuOptions

Outlines additional options for configuring the DFU process.

Prop	Type	Description	Default	Since
disableNotification	boolean	Sets whether the progress notification in the status bar should be disabled.	false	1.0.0
startAsForegroundService	boolean	Sets whether the progress notification in the status bar should be disabled.	false	1.0.0
keepBond	boolean	Sets whether the bond information should be preserver after flashing new application.	false	1.0.0
restoreBond	boolean	Sets whether a new bond should be created after the DFU is complete. The old bond information will be removed before.	false	1.0.0
dataObjectDelay	number	Sets the initial delay (in milliseconds) that the service will wait before sending each data object.	0	1.0.0
packetReceiptNotificationsEnabled	boolean	Enables or disables the Packet Receipt Notification (PRN) procedure. By default the PRNs are disabled on devices with Android Marshmallow or newer and enabled on older ones.		1.0.0
packetsReceiptNotificationsValue	number	If Packet Receipt Notification procedure is enabled, this method sets the number of packets to be sent before receiving a PRN.	12	1.0.0
forceDfu	boolean	Setting force DFU to true will prevent from jumping to the DFU Bootloader mode in case there is no DFU Version characteristic (Legacy DFU only!). Use this if the DFU operation can be handled by your device running in the application mode. This method is ignored in Secure DFU.	false	1.0.0
rebootTime	number	Sets the time (in milliseconds) required by the device to reboot. The library will wait for this time before scanning for the device in bootloader mode.	0	1.0.0
scanTimeout	number	Sets the scan duration (in milliseconds) when scanning for DFU Bootloader.	5000	1.0.0
forceScanningForNewAddressInLegacyDfu	boolean	When this is set to true, the Legacy Buttonless Service will scan for the device advertising with an incremented MAC address, instead of trying to reconnect to the same device.	false	1.0.0
disableResume	boolean	This options allows to disable the resume feature in Secure DFU. When the extra value is set to true, the DFU will send Init Packet and Data again, despite the firmware might have been send partially before. By default, without setting this extra, or by setting it to false, the DFU will resume the previously cancelled upload if CRC values match.	false	1.4.0
numberOfRetries	number	Sets the number of retries that the DFU service will use to complete DFU.	0	1.0.0
mtu	number	Sets the Maximum Transfer Unit (MTU) value that the Secure DFU service will try to request before performing DFU. Available for Android only. By default, value 517 will be used, which is the highest supported y Android. However, as the highest supported MTU by the Secure DFU from SDK 15 (first which supports higher MTU) is 247, the sides will agree on using MTU = 247 instead if the phone supports it (Lollipop or newer device).		1.0.0
currentMtu	number	Sets the current MTU value. This method should be used only if the device is already connected and MTU has been requested before DFU service is started. Available for Android only.	23	1.0.0
disableMtuRequest	boolean	Disables MTU request. Available for Android only.	false	1.4.0
scope	number	This method allows to narrow the update to selected parts from the ZIP, for example to allow only application update from a ZIP file that has SD+BL+App. System components scope include the Softdevice and/or the Bootloader (they can't be separated as they are packed in a single bin file and the library does not know whether it contains only the softdevice, the bootloader or both) Application scope includes the application only.		1.0.0
mbrSize	number	This method sets the size of an MBR (Master Boot Record). It should be used only when updating a file from a HEX file. If you use BIN or ZIP, value set here will be ignored.	4096	1.0.0
unsafeExperimentalButtonlessServiceInSecureDfuEnabled	boolean	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.	false	1.0.0

PermissionStatus

Represents the current status of permissions in the plugin.

Prop	Type	Description	Since
notifications	PermissionState	Indicates the permission state of notifications.	1.0.0

PluginListenerHandle

Prop	Type
remove	() => Promise<void>

DfuUpdate

The DFU update object that is passed to the DFUStateChanged event

state	DfuState	Defines the structure for the DFU update object passed to the DFUStateChanged event.	1.0.0
data	DfuUpdateData	The DFU data that is passed to the DfuUpdate object	1.0.0

DfuUpdateData

speed	number	The current speed in bytes per millisecond.	1.0.0
avgSpeed	number	The average speed in bytes per millisecond.	1.0.0
currentPart	number	The number of parts being sent. In case the ZIP file contains a Soft Device and/or a Bootloader together with the application the SD+BL are sent as part 1, then the service starts again and send the application as part 2.	1.0.0
partsTotal	number	The total number of parts.	1.0.0
duration	number	The total time elapsed since the start of the DFU process in milliseconds	1.1.0
