Bluetooth Versions




Version 1.1 and earlier



Since the technology of Bluetooth was introduced in



1998, several specification versions have been



released. Versions 1.0 and 1.0B had too many issues



and problems for manufacturers to develop devices



for Bluetooth. The main issue was the lack of



communication among the devices.





The core specification version 1.1 is the first



successful operating version of Bluetooth. Version



1.1 corrected a majority of the bugs and problems



found in earlier versions.





Version 1.2



Many of the newer Bluetooth devices, such as the



newer cell phones are being sold with the newer



Bluetooth version 1.2. This version offers backward



compatability with Bluetooth 1.1, faster transmission



speeds, received signal strength, and a host



controller interface (HCI) support for 3 wire UART.





Bluetooth version 2.0



It's true that there may be multiple communication



technologies, although they all share one common



trait - faster is better. Bluetooth specialists



realized this, and therefore worked on improving



the speeds of version 1.2. The newest version,



version 2.0 + EDR (Enhanced Data Rate) was



accounced in 2004 and became available in late



2005.





Version 2.0 delivers data transfer rates of up



to three times that of the original version of



Bluetooth. Version 2.0 also provides enhanced



connectivity. With Bluetooth 2.0 + EDR, you'll



be able to run more devices at the same time -



with more efficiency.





Computers and even computer related devices are



expected to be some of the first devices to



encorporate Bluetooth 2.0 + EDR, followed of



course by audio and imaging devices.





Version 2.0 is backward compatible with previous



versions, three times faster, and offers an



enhanced data rate of 2.1 MB a second. It also



offers broadcast and multicast support, along



with a further enhanced bit error rate



performance, making it the best Bluetooth has
