Flutter plugin that allows to find bluetooth devices & send raw bytes data. Supports both Android and iOS.
Inspired by bluetooth_print.
List<int> bytes data to a deviceFor a full example please check /example folder. Here are only the most important parts of the code to illustrate how to use the library.
BluetoothManager bluetoothManager = BluetoothManager.instance;
BluetoothDevice _device;
bluetoothManager.startScan(timeout: Duration(seconds: 4));
bluetoothManager.state.listen((state) {
switch (state) {
case BluetoothManager.CONNECTED:
// ...
break;
case BluetoothManager.DISCONNECTED:
// ...
break;
default:
break;
}
});
// bluetoothManager.scanResults is a Stream<List<BluetoothDevice>> sending the found devices.
// _device = <from bluetoothManager.scanResults>
await bluetoothManager.connect(_device);
List<int> bytes = latin1.encode('Hello world!\n').toList();
await bluetoothManager.writeData(bytes);
await bluetoothManager.disconnect();
