First created as a way to replace cables and such, today many of the gadgets in the market have this technology built into their systems. While the technology is dominant, and most certainly convenient, not a large number of people know how the process works exactly.Though initial development began in 1994, the idea of Bluetooth technology was officially unveiled and the Bluetooth Special Interest Group (SIG) was formed in September of 1998. The Bluetooth SIG is a group consisting of the leading states of the telecommunications, network, and computing industries. The members of this group is liable for the continuous growth and development of Bluetooth technology. In 1999, the first working versions of Bluetooth technology came on the market. At this time, however, the technology was still in its early stages, and it didn’t take off until a number of years later.I could hardly believe it!In 2003, the Bluetooth SIG announced the complete overhaul of the Bluetooth Core Specification, and in 2004, Version 2.0 with Enhanced Data Rate (EDR) was introduced. This new version drastically increased the rate of data transfer. It was what truly turned Bluetooth into a common household name. In 2005, devices that were compatible with Version 2.0 + EDR began hitting the shelves around the world. The introduction of Version 2.1 + EDR further revolutionized the technology by making it more secure and easier to use. This new version also made the pairing of Bluetooth devices easier than ever before. In 2009, Bluetooth Version 3.0 + High Speed (HS) became available. This new version makes transfers even faster whenever WiFi access is available. Finally, 2010 saw the release of Bluetooth Version 4.0. This version supports both high speed and Classic Bluetooth as well as the new low energy protocols. The low energy functionality is intended for very low power applications that run off of a coin cell battery.Investigating Bluetooth DevicesIn this article, I will be mainly focusing on bluetooth audio devices and the process under which it all comes together. I will not be using any confusing terminology in this paper, this is only meant to scratch the surface. I am using bluetooth audio devices in my examples, because they’re common, and it is easier to relate examples and/or situations to you as the reader by using devices that you interact with everday.In a nutshell, bluetooth audio streaming is simply two bluetooth capable devices communicating together to deliver you some sort of auditory information. Sounds simple enough, right? The most common usage or form of this technology at work, usually involves a ‘source,’ such as a mobile phone, a computer, an MP3 player, or a laptop. The ‘source,’ then, communicates wirelessly, via radio wav
