BluetoothAdapter.LeScanCallback

An interface required delivering the results of LE Scan. You need to implement the method onLeScan() which will return back scanned device, its RSSI (signal strength) and the scan record array. Later this object will be passed to the startLeScan method.

BluetoothAdapter.LeScanCallback leScanCallback = new BluetoothAdapter.LeScanCallback() {     @Override     public void onLeScan(BluetoothDevice device, int rssi, byte[] scanRecord) {          // Do something with the scanned data...     } }; startLeScan(leScanCallback);
