Bluetooth 2.0

Bluetooth 2.0

This version, specified on 10th November 2004 is backward-compatible with 1.1. The main enhancement is the introduction of an EDR of 3.0 Mbit/s. This has the following effects

  • Three times faster transmission speed—up to 10 times in certain cases (up to 2.1 Mbit/s).
  • Lower power consumption through a reduced duty cycle.
  • Simplification of multi-link scenarios due to more available bandwidth.

The practical data transfer rate is 2.1 megabits per second and the basic signalling rate is about 3 megabits per second

The "Bluetooth 2.0 + EDR" specification given at the Bluetooth Special Interest Group (SIG) includes EDR and there is no specification "Bluetooth 2.0" as used by many vendors. The HTC TyTN pocket PC phone, shows "Bluetooth 2.0 without EDR" on its data sheet and another source states Bluetooth 2.0 without EDR is equivalent to version 1.2 with additional bug fixes. In many cases it is not clear whether a product claiming to support "Bluetooth 2.0" actually supports the EDR higher transfer rate.
