A full data sheet will do you no good for wireless devices. Wireless devices 
employ a HAL (hardware abstraction layer) that is meant to restrict people 
from doing un-regulated things with the chip. People like the FCC require 
some level of assurance that the distributor is not providing hardware that 
can be used outside its tested parameters. Basically, I would not bother 
unless you are pretty deep into reverse engineering.
