Bluetooth 1.2
- Backward compatible with 1.1
- Baseband platform already available from Ericsson Techonology Licensing
- Adaptative Frequency Hopping (AFH) provides better immunity to interference from other devices (such as 802.11 devices)
- Scatternet ability (Running multiple Piconets simultaneously, making it possible to interconnect piconets)
- Extended SCO (ESCO) (whatever that means)
- Improved QoS
- Faster connections then in 1.1
Bluetooth 2.0
First news/rumors
- Backward compatible with 1.1 and 1.2
- This version is rumored to contain new speeds of 4,8 and 12 Mbps.
- A new way of communication: non-hopping narrowband connections, which sounds like a broadcast channel that can be read by all devices in the coverage area.
- 2.0 dispenses with the master/slave situation making every device able to keep a piconet running, while as in the 1.1 spec if the master leaves the piconet is dropped for all slaves
- The release of the 2.0 specification will propably be delayed to 2004, even though there are already prototypes running in Ericssons labs
