Bluetooth shield problem

So I am trying to get it working.
It was working, but I have not been using it for a while. Now I cant get it to work - it flashes green led and do not switch itself to inq. I tried different baudrates, still no luck. It always says “-1” if I reading the serial. Any ideas?

Dear customer,
Firstly , please check if the jumper you have put is right like picture of wiki .
And then , you can download thetemplate code and try to use difference baudrete by change the following code till the red and green LED flash in turn.
