Bluetooth ACTION_FOUND broadcastReceiver is not working

I finally found answer. Android 6.0 needs additional permission, but Just adding uses-permission to Manifest is not working. You have to check permission to user. I write my code like this:

int permissionCheck = ContextCompat.checkSelfPermission(thisActivity, Manifest.permission.ACCESS_COARSE_LOCATION);

        BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
        if (!bluetoothAdapter.isEnabled())
          bluetoothAdapter.enable();
        leScanner = bluetoothAdapter.getBluetoothLeScanner();

        Button boton = (Button) findViewById(R.id.button1);
        boton.setOnClickListener(new OnClickListener(){
            public void onClick(View v) {
                leScanner.startScan(scanCallback);
            }
        });

This code show you permission pop up. Thanks for many answers.

You need a force request of ACCESS_COARSE_LOCATION permission:

if (ContextCompat.checkSelfPermission(activity, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
    ActivityCompat.requestPermissions(activity, new String[]{Manifest.permission.ACCESS_COARSE_LOCATION}, PERMISSION_REQUEST_CODE);
}

BluetoothAdapter bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
