startLeScan replacement to current api

Question

Goal is to read the values of a bluetooth LE heart rate monitor.

Using google\'s sample, I get

private void scanLeDevice(final boolean enable) {
             


        

Answer 1

Thank you all for your responses. To Summarize the answer to this question I'll add my final code snippet.

private BluetoothAdapter mBluetoothAdapter;


private ScanCallback mLeScanCallback = new ScanCallback() {
    @Override
    public void onScanResult(int callbackType, ScanResult result) {
        super.onScanResult(callbackType, result);
    }

    @Override
    public void onBatchScanResults(List results) {
        super.onBatchScanResults(results);
    }

    @Override
    public void onScanFailed(int errorCode) {
        super.onScanFailed(errorCode);
    }
};

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    BluetoothManager bluetoothManager = (BluetoothManager) getActivity().getSystemService(Context.BLUETOOTH_SERVICE);
    mBluetoothAdapter = bluetoothManager.getAdapter();
}


private void scanLeDevice(final boolean enable) {

    final BluetoothLeScanner bluetoothLeScanner = mBluetoothAdapter.getBluetoothLeScanner();

    if (enable) {
        // Stops scanning after a pre-defined scan period.
        mHandler.postDelayed(new Runnable() {
            @Override
            public void run() {
                mScanning = false;

                bluetoothLeScanner.stopScan(mLeScanCallback);
            }
        }, SCAN_PERIOD);

        mScanning = true;
        bluetoothLeScanner.startScan(mLeScanCallback);
    } else {
        mScanning = false;
        bluetoothLeScanner.stopScan(mLeScanCallback);
    }
}
