Hi,
I have been trying to use this module and I want to save power when I am not transmitting.
Here is the user manual - http://www.sparkfun.com/datasheets/Wireless/Bluetooth/rn-bluetooth-um.pdf

Now My requirements are these
1. keep the module connected to my pc
2. transmit "Hello" to pc when a button pin 12 goes high on the arduino, this will happen by button press

So when I am not transmitting, I want to be able to keep the device in sleep mode. The command for that is SW,8000
However my module is still consuming 25 miliamps when not transmitting. Has anyone tried this?
