Android 与蓝牙键盘两种方式都连接不上，可是与hc06可以连接，uuid的问题还是其他问题

class ItemClickEvent implements AdapterView.OnItemClickListener {

    @Override

        uuid = UUID.fromString(SPP_UUID);
        Log.e("uuid",uuid.toString());

        BluetoothDevice btDev = btAdapt.getRemoteDevice(address);//"00:11:00:18:05:45"
