Can we put WT-11 on Arduino BT in Deep Sleep mode?

I am using the Arduino BT and searching for command to put the BlueTooth into Deep Sleep Mode or Idle mode (Arduino Alpha) to save the power, but could not find it anywhere.

  • Can someone help me on it?
  • If YES, then what is the command to wake the Bluetooth WT-11 up later?

Thanks to any help :-?
