flutter_nordic_dfu

Description:

flutter nordic dfu

flutter-nordic-dfu #
This library allows you to do a Device Firmware Update (DFU) of your nrf51 or
nrf52 chip from Nordic Semiconductor. It works for Android and iOS fine.
This is the implementation of the reference "react-native-nordic-dfu"
For more info about the DFU process, see: Resources
Run Example-->Amazing #


Add your dfu zip file to example/assets/file.zip


Run example project


Scan device


Start dfu


Usage #
startDFU #
Examples
You can pass an absolute file path or asset file to FlutterNordicDfu
Use absolute file path
/// You can define your ProgressListenerListener
await FlutterNordicDfu.startDfu(
'EB:75:AD:E3:CA:CF', '/file/to/zip/path/file.zip',
progressListener: ProgressListenerListener(),
);


class ProgressListenerListener extends DfuProgressListenerAdapter {
@override
void onProgressChanged(String deviceAddress, int percent, double speed,
double avgSpeed, int currentPart, int partsTotal) {
super.onProgressChanged(
deviceAddress, percent, speed, avgSpeed, currentPart, partsTotal);
print('deviceAddress: $deviceAddress, percent: $percent');
}
}

/// Or you can use DefaultDfuProgressListenerAdapter
await FlutterNordicDfu.startDfu(
'EB:75:AD:E3:CA:CF',
'assets/file.zip',
fileInAsset: true,
progressListener:
DefaultDfuProgressListenerAdapter(onProgressChangedHandle: (
deviceAddress,
percent,
speed,
avgSpeed,
currentPart,
partsTotal,
) {
print('deviceAddress: $deviceAddress, percent: $percent');
}),
);

Use asset file path
/// just set [fileInAsset] true
await FlutterNordicDfu.startDfu(
'EB:75:AD:E3:CA:CF', 'assets/file.zip',
progressListener: ProgressListenerListener(),
fileInAsset: true,
);

class ProgressListenerListener extends DfuProgressListenerAdapter {
@override
void onProgressChanged(String deviceAddress, int percent, double speed,
double avgSpeed, int currentPart, int partsTotal) {
super.onProgressChanged(
deviceAddress, percent, speed, avgSpeed, currentPart, partsTotal);
print('deviceAddress: $deviceAddress, percent: $percent');
}
