Bluetooth: Operation and Use by R. Morrow:
Author is a Besser instructor for a Bluetooth course
Besser Associates Bluetooth course:
"This three-day course introduces and analyzes Bluetooth wireless networking, based on Bluetooth specification 2.1 + EDR (enhanced data rate). Participants begin by studying Bluetooth signal propagation characteristics, modulation, packet structure, data and audio processing, and error control. The role of the Bluetooth link manager in establishing a connection and implementing security and encryption measures are then discussed. Various higher layers in the Bluetooth protocol stack are examined such as packet segmentation and reassembly, service discovery, the host controller interface, and the implementation of application profiles. The Bluetooth qualification program is discussed. Finally, the ability of Bluetooth to coexist with other wireless networks in the 2.4 GHz band is analyzed"
