We will skip the rest of the profiles, except to mention that some profiles
serve as building blocks on which the above profiles are built. The generic access
profile, on which all of the other profiles are built, provides a way to establish and
maintain secure links (channels) between the master and the slaves. The other
generic profiles define the basics of object exchange and audio and video transport. Utility profiles are used widely for functions such as emulating a serial
line, which is especially useful for many legacy applications.
