I'm wondering if the following is possible: i'd like to set up an arduino board with a bluetooth module where I can have access to low(er) level bluetooth protocols --specifically I'd like to run a BT inquiry and retrieve a list of BT devices in range with their BD_ADDR and (if possible) their radio link strength (to estimate distance).
What I DON'T need to do is actually transfer data or establish links between BT devices, I just want to know "who" is in range.
While searching I found lots of info on arduino BT shields/components that have direct serial port access to BT serial connections, but I don't know if these would allow the lower level BT access I need.
Now I don't want to implement the whole BT stack, of course ;)
Ideally there would be some arduino compatible BT shield with a nice driver stack that allows access to the BT link control inquiry function and return the results.
Any information and/or links to hardware/sw that meets allows that functionality that would be greatly appreciated.
