Chapter 2 — Bluetooth Overview
2-1 Introduction to Bluetooth
Bluetooth Overview
Bluetooth is an open protocol for short-range wireless and data communication between fixed
or mobile devices over distances of up to 10 meters. It operates on the globally unlicensed
ISM frequency band at 2.4 GHz. The Bluetooth standard is defined by an open specification
available publicly and royalty free.
Bluetooth Special Interests Group
The Bluetooth Special Interest Group (SIG) oversees the development of the Bluetooth
standard and the licensing of the Bluetooth technologies and trademarks. The SIG is a
not-for-profit trade association founded in 1998. Today the SIG has more than 23,000
member companies from a wide cross-section of business sectors.
Bluetooth Qualification
To gain recognition as a Bluetooth enabled product, all products (manufacturers) must pass
through a nine step qualification process.
1. Join the Special Interest Group (SIG).
2. Enter the Qualification Listing Interface (QLI) on the Bluetooth.org website.
3. Obtain a Qualification Design ID (QD ID).
4. Define supported features; the Test Plan Generator (TPG) automatically generates a
suite of required test cases, RF and Protocol.
5. Execute tests as defined above.
6. Log results from tests in the Test Report Declaration (TRD).
7. Complete Declaration of Compliance (DoC) and additional information as required.
8. Complete payment of fees.
9. Product is listed on Qualified Product List (QPL) and End Product List (EPL).
Master and Slave Devices
When Bluetooth enabled devices communicate, one device acts as the ‘master’ (issuing
clocking and hopping sequence instructions) and the other(s) act as ‘slave’ device. A master
device can communicate with up to seven slave device in an ad-hoc network known as a
piconet. Data can be transferred between the master device and any other slave device in the
piconet but the roles are not fixed and any slave may take on the role of the master device as
required.
