Detecting Devices Within a scatternet.

Hi everybody,

Is there a way that we could detect the devices connected in a piconet within the scatternet connection?

Example piconet A Wants to know what the devices connected in D, which is not a range of A, via B and C, which are within 10 meters. A is a range of B, B is arrange of C and C is a range D.

Thank you?
