The existing versions are1.0, 1.2, 2.0+EDR.
Bluetooth Version 2.0 EDR (Enhanced Data Rate)
The Bluetooth Special Interest Group (SIG) which was lately established in September 1998 a private assosiation thought to upgrades it earlier version 1.2 and in June 2004, Bluetooth SIG successfully announced the version 2.0 EDR and the Bluetooth SIG has finally launch its new upgraded version in the year 2005 and from since then Bluetooth version 2.0+EDR is available in the market.
