Ericsson Offers Bluetooth 1.2 Software Stack

- Ericsson Technology Licensing announced their new Core Bluetooth software stack, B-C3, today. The new stack is the first on the market supporting Bluetooth 1.2 features and profiles. The company announced cores for Bluetooth 1.2 baseband and radio last year, which means the software stack completes their offering.

The stack supports standard 1.2 features such as Adaptive Frequency Hopping (AFH) and extended Synchronous Connection-oriented link (eSCO). Both are features that improve voice quality. The stack also supports parallel applications; using the Bluetooth connection for more than one activity at the same time.

The Ericsson Core Bluetooth Software Stack B-C3 will be qualified and generally available mid-March 2004, and is now being shipped to selected customers. It will also be available for evaluation in a Microsoft Windows® environment.
