Hello. I am relatively new to arduino, and want to do something that should be simple, but I am finding it is not.
I have an arduino duemilanove board with bluesmirf gold module wired to it. I want this device to detect any bluetooth devices in range. If it detects a bluetooth device with the right bluetooth address, I want it to perform and action.
I can't seem to find anywhere what I need/ code to get the module to detect bluetooth devices?!
Any help or sample code would be much appreciated 
You'll need to dig through the bluesmirf datasheet, see what commands it accepts.. and how.
The bluetooth devices I've worked with thus far all used a serial interface, and came with a comprehensive manual containing the entire AT command set the device accepts.
I don't know how the bluesmirf works in particular, so I'll leave it to you to do the research to find out the specifics.
