Fitness startBleScan successful but scan Stopped with MI Band 2

I want to make sensor request to my mi band 2 from my app real time. I have some difficulties with this. I use permissions BLUETOOTH and BLUETOOTH_ADMIN. I checked that I can see my device via bluetooth le default api. I try to use this example https://developers.google.com/fit/android/ble-sensors?hl=ru and all the time I get onScanStopped and this callback dont have some explanation, so I dont understand why it failes. My code:

GoogleApiClient client = new GoogleApiClient.Builder(this)
                    .addApi(Fitness.SENSORS_API)
                    .addScope(new Scope(Scopes.FITNESS_ACTIVITY_READ))
                    .addScope(new Scope(Scopes.FITNESS_BODY_READ))
                    .addConnectionCallbacks(this)
                    .addOnConnectionFailedListener(this)
                    .build();
            client.connect();

And onConnected I have:

Fitness.getBleClient(this, GoogleSignIn.getLastSignedInAccount(this))
.startBleScan(Arrays.asList(DataType.TYPE_ACTIVITY_SEGMENT), 60, bleScanCallbacks)
        .addOnCompleteListener(new OnCompleteListener<Void>() {
            @Override
            public void onComplete(@NonNull Task<Void> task) {
                Log.d("TAG_F", "onComplete: " + task.isSuccessful());
            }
        });

Here I also tries all of this data types DataType.TYPE_STEP_COUNT_DELTA, DataType.TYPE_HEART_RATE_BPM

This shows me that my scan is successful. But on callback after 60 seconds I get onScanStopped :

private BleScanCallback bleScanCallbacks = new BleScanCallback() {
        @Override
        public void onDeviceFound(BleDevice bleDevice) {
            Log.d("TAG_F", "onDeviceFound: " + bleDevice.getDataTypes());

        }

        @Override
        public void onScanStopped() {
            Log.d("TAG_F", "onScanStopped: ");
        }
    };
