Bluetooth 1.2
This version is backward-compatible with 1.1 and the major enhancements include the following:
Faster Connection and Discovery
Adaptive frequency-hopping spread spectrum (AFH), which improves resistance to radio frequency interference by avoiding the use of crowded frequencies in the hopping sequence.
Higher transmission speeds in practice, up to 721 kbit/s, as in 1.1.
Extended Synchronous Connections (eSCO), which improve voice quality of audio links by allowing retransmissions of corrupted packets.
Host Controller Interface (HCI) support for three-wire UART.
Bluetooth 2.0
This version, specified in November 2004, is backward-compatible with 1.1. The main enhancement is the introduction of an enhanced data rate (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.
Further improved (bit error rate) performance.
