Bluetooth Profiles
One of the key Bluetooth design goals is to offer a direct replacement for cables
between electronic devices. In order to make the transition as easy as possible
for existing devices and software that were never designed to use a wireless radio
link (legacy devices), Bluetooth emulates various types of physical links, such as
a serial cable, etc. These are called
Profiles
.
When your Palm/blueM discovers and pairs with another Bluetooth device, you
will be presented with a list of profiles supported by that device. The most likely
choices that will be offered are as follows:
•
Serial
– One of the most basic yet most used profiles, this mode emu-
lates a simple RS232 serial cable link between two devices. This profile
forms the basis of several other profiles.
•
Dial-Up Network (DUN)
– Recreates the conditions under which applica-
tions such as web browsers and email packages use a modem link to gain
access to the Internet.
The one to choose depends upon the kind of device that you are connecting to
and what you wish to do with it.
