AndroidBluetoothLibrary
A Library for easy implementation of Serial Bluetooth Classic and Low Energy on Android.
- Bluetooth Classic working from Android 2.1 (API 7)
- Bluetooth Low Energy working from Android 4.3 (API 18)
Use
Configuration
Bluetooth Classic
BluetoothConfiguration config = new BluetoothConfiguration();
config.context = getApplicationContext();
config.bluetoothServiceClass = BluetoothClassicService.class;
config.bufferSize = 1024;
config.characterDelimiter = '\n';
config.deviceName = "Your App Name";
config.callListenersInMainThread = true;
config.uuid = UUID.fromString("00001101-0000-1000-8000-00805f9b34fb"); // Required
BluetoothService.init(config);Bluetooth Low Energy
BluetoothConfiguration config = new BluetoothConfiguration();
config.context = getApplicationContext();
config.bluetoothServiceClass = BluetoothLeService.class;
config.bufferSize = 1024;
config.characterDelimiter = '\n';
config.deviceName = "Your App Name";
config.callListenersInMainThread = true;
config.uuidService = UUID.fromString("e7810a71-73ae-499d-8c15-faa9aef0c3f2"); // Required
config.uuidCharacteristic = UUID.fromString("bef8d6c9-9c21-4c9e-b632-bd58c1009f9f"); // Required
config.transport = BluetoothDevice.TRANSPORT_LE; // Required for dual-mode devices
config.uuid = UUID.fromString("00001101-0000-1000-8000-00805f9b34fb"); // Used to filter found devices. Set null to find all devices.
BluetoothService.init(config);Getting BluetoothService
BluetoothService service = BluetoothService.getDefaultInstance();Scanning
service.setOnScanCallback(new BluetoothService.OnBluetoothScanCallback() {
@Override
public void onDeviceDiscovered(BluetoothDevice device, int rssi) {
}
@Override
public void onStartScan() {
}
@Override
public void onStopScan() {
}
});
service.startScan(); // See also service.stopScan();Connecting
service.setOnEventCallback(new BluetoothService.OnBluetoothEventCallback() {
@Override
public void onDataRead(byte[] buffer, int length) {
}
@Override
public void onStatusChange(BluetoothStatus status) {
}
@Override
public void onDeviceName(String deviceName) {
}
@Override
public void onToast(String message) {
}
@Override
public void onDataWrite(byte[] buffer) {
}
});
service.connect(device); // See also service.disconnect();Writing
BluetoothWriter writer = new BluetoothWriter(service);
writer.writeln("Your text here");Complete example

...
</manifest>Known Issues / Troubleshooting
- Scanning will not detect bluetooth devices if the user has denied Location Privacy Permission to your app. This library does not test for the permission and will not raise errors. (Android 6.0+) See: http://stackoverflow.com/a/33045489/2826279
