Versions of the Bluetooth Specification
The Bluetooth specification version 1.0A was made publicly available in July 1999. In December of that year, version 1.0B, which contained corrections and clarifications from the original version, was published. In February 2001 version 1.1 became publicly available on the Bluetooth Special Interest Group (SIG) Web site, http://www.bluetooth.com, and as of this writing, it is the most current version of the specification.
The SIG continues to enhance the specification, and many anticipate a "version 2.0" publication of the specification. However, this is not the SIG's intent. Instead, the SIG is developing new profiles and other specification enhancements, with plans to publish each addition as it is completed. These new additions to the specification are sometimes informally called "version 2.0," but in fact, there are no plans to publish a major specification revision in the near future. This does not mean that the upcoming profiles and other specification updates are not important, however. In fact, many will enable exciting new usage cases for Bluetooth wireless technology. Here, we examine just a few of the areas in which work is currently underway in the SIG.
