DFRobot Bluetooth Bee 2.0 with Arduino Fio programming help


I am a newbie in programming the Arduino Fio with the Bluetooth Bee and I would really appreciate some help with that. My problem is that I tried to program the Bluetooth Bee using the AT commands but I cannot even get a response to the simple AT test command. When I write it to the serial monitor there is no answer at all. Is some kind of basic sketch needed to configure the Bluetooth Bee first? Any help would be greatly appreciated.

Here is a link to the datasheet and a page about the bluetooth bee I am using:
