WinBle #

Use the WinBle plugin to enable Bluetooth Low Energy in Flutter Windows and pure Dart projects (Windows only)
Usage #
First initialize WinBle, to initialize on Flutter Windows, get server path using await WinServer.path, and for pure dart projects ( Windows only ) Download BleServer.exe file and place in the same folder, checkout example_dart for more details
// To initialize on Flutter Windows
await WinBle.initialize(serverPath: await WinServer.path());

// For pure dart projects
await WinBle.initialize(serverPath: "Path of BLEServer.exe file");

To Start Scan
WinBle.startScanning();

StreamSubscription? scanStream = WinBle.scanStream.listen((event) {
// Get Devices Here
});
copied to clipboard
To Stop Scan
WinBle.stopScanning();

scanStream?.cancel();

To Connect
// To Connect
await WinBle.connect(address);

// Get Connection Updates Here
StreamSubscription _connectionStream =
WinBle.connectionStreamOf(device.address).listen((event) {
// event will be a boolean , in which
// true => Connected
// false => Disconnected
});

To Disconnect
await WinBle.disconnect(address);

To get MaxMtuSize
await WinBle.getMaxMtuSize(address);

Handle Bluetooth radio
// To get rdaio status
WinBle.getBluetoothState();

// To get updates of radio state
WinBle.bleState.listen((BleState state) {
// Get BleState (On, Off, Unknown, Disabled, Unsupported)
});

// To turn on radio
WinBle.updateBluetoothState(true);

// To turn off radio
WinBle.updateBluetoothState(false);

Pairing Options
// To Pair
await WinBle.pair(address);

// To UnPair
await WinBle.unPair(address);

// To Check if Device can be Paired
bool canPair = await WinBle.canPair(address);

// To Check if Device is Already Paired
bool isPaired = await WinBle.isPaired(address);

Rest All Methods are
// To Get Services
var services = await WinBle.discoverServices(address);

// To Get Characteristic
List<BleCharacteristic> bleCharacteristics = await WinBle.discoverCharacteristics(address: address, serviceId: serviceID);

// To Read Characteristic
List<int> data = await WinBle.read(address: address, serviceId: serviceID, characteristicId: charID);

// To Write Characteristic
await WinBle.write( address: address, service: serviceID, characteristic: charID, data: data, writeWithResponse: writeWithResponse);

// To Start Subscription
await WinBle.subscribeToCharacteristic(address: address, serviceId: serviceID, characteristicId: charID);

// To Stop Subscription
await WinBle.unSubscribeFromCharacteristic(address: address, serviceId: serviceID, characteristicId: charID);

// Get Characteristic Value Updates Here
StreamSubscription _characteristicValueStream = WinBle.characteristicValueStream.listen((event) {
// Here We will Receive All Characteristic Events
});
