Ble信标配对在棉花糖中不起作用

Question

For my application, I'm trying to programmatically pair with Ble Beacon using BluetoothGatt API.I can able to pair with Ble beacon up to lollipop.But i cannot pair in Marshmallow(My testing device is oneplus 3).

Also, i gave ACCESS_COARSE_LOCATION,ACCESS_FINE_LOCATION permission in the manifest file and turned on GPS location.

BluetoothGatt mGatt; 
baBluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
public void connectToDevice(String sMacId) {        

    BluetoothDevice device = baBluetoothAdapter.getRemoteDevice(sMacId);       

    if (mGatt == null) {
        mGatt = device.connectGatt(this, false, gattCallback);
    }
}

This is my BluetoothGatt callback method.After calling discoverServices(),it is directly going to BluetoothProfile.STATE_DISCONNECTED case.

private final BluetoothGattCallback gattCallback = new BluetoothGattCallback() {
    @Override
    public void onConnectionStateChange(BluetoothGatt gatt, int status, int newState) {

        switch (newState) {
            case BluetoothProfile.STATE_CONNECTED:
                Log.e("gattCallback", "STATE_CONNECTED");
                gatt.discoverServices();
                break;
            case BluetoothProfile.STATE_DISCONNECTED:
                Log.e("gattCallback", "STATE_DISCONNECTED");
                break;
            default:
                Log.e("gattCallback", "STATE_OTHER");
        }
    }
}

I also tried in native bluetooth.But it showing error.My beacon pairing password is 123456.This password is working less than marshmallow.Please help me! Please see this image link

If someone is still looking for a solution for this, see this answer on stackoverflow.com adding gatt.connect() after mDevice.connectGatt(mContext, false, mBluetoothGattCallback); did the trick.
