| HEADS UP: Our discussion on the
Bluetooth protocol is somewhat technical and rather dry.
We know this site is supposed to provide easy-to-use
information and advice about Bluetooth technology and products, but it is “the comprehensive
guide to everything Bluetooth related”. So, in order to be
as comprehensive as possible, we have to talk about the
protocol. We will try our best to make it as simple and
condensed as possible. |
Bluetooth technology must be examined in
two separate sections in order for you to understand the entire
process of how the technology works and how it is used.
* The Bluetooth protocol defines how the
wireless technology works, and
* The Bluetooth Profiles describe and
organize how the technology is used.
In this section we will be discussing
the Bluetooth protocol (Bluetooth Profiles are examined in another section).
- Overview of the Bluetooth Protocol
The Bluetooth standard requires a basic
level of communication between devices, so that they can connect
to each other over the airwaves, at the correct frequencies,
using the correct channels, and finding the correct
destination(s). In order to create this basic level of
communication, a specific protocol was created. The Bluetooth
protocol establishes the set of rules by which all Bluetooth
devices must abide in order to establish a connection to
communicate with one another.
Most protocols, Bluetooth’s included, are usually layered
together into “protocol stacks”, and the various tasks
are split up and assigned to the different layers of protocols in
the stack. Think of it like an organization or company that is
located in an office building with multiple floors. The building
is organized so that each floor is a different department within
the company. Each department has separte duties and
responsibilites, but each department is necessary for the entire
organization to function as a whole.
Bluetooth's protocol has several "departments", which are referred to as levels.
