Significant Bluetooth Releases To Date

Bluetooth 4.x

This version has both Bluetooth Classic and Bluetooth Smart (Low Energy) Support. This release brough about the rems “Low Energy” and “Smart” devices. By including new low-power profiles, Bluetooth devices can be built to extend battery life significantly.  Additionally, profiles for Bluetooth Low Energy (BTLE / BLE) may be custom made or used from a library found at the Bluetooth SIG.

Version 4.1 of the Bluetooth specification provided one significant step in the ability to allow devices to support multiple roles simultaneously, giving rise to "mesh" networking.

Version 4.2 introduced three major updates to the specification: Low Energy data packet length extensions (from 27 to 251 bytes), Low Energy privacy upgrades and Low Energy secure connections.

Bluetooth 2.1 + EDR

Adopted in 2007, this version of Bluetooth added Secure Simple Pairing (SSP) to improve the pairing experience for Bluetooth devices and also increased relative security strength.

Bluetooth 2.0

Released in 2004, this version is backwards compatible with 1.x. The main enhancement is the introduction of Enhanced Data Rate (EDR) of 2.1 Mbit/s.

This has the following effects (Bluetooth SIG, 2004):

  • 3 times faster transmission speed (up to 10 times in certain cases).
  • Lower power consumption through a reduced duty cycle.
  • Simplification of multi-link scenarios due to more available bandwidth.
  • Further improved BER (bit error rate) performance.
