The Bluetooth SIG has aimed from the start to ensure that developers and users do not concern themselves with updated version of the Bluetooth specification, but rather concern themselves on implementation of the existing Bluetooth 1.1 spec and the use/development of profiles. This is to ensure that developers do not wait for later spec versions and that confusion and interoperability problems do not enter the marketplace. However, the recent release of cores based on preliminary Bluetooth 1.2 and speculation on the abilities of Bluetooth 2.0, means that far-sighted developers should not stand still in approaching Bluetooth optimisations. This article explains the features on a broad level of Bluetooth 1.2 and examines the reports on Bluetooth 2.0.
