Bluetooth Module

The Bluegiga WT12 module is a next-generation, class 2, Bluetooth 2.0 plus EDR module. The WT12 is a highly integrated and sophisticated Bluetooth module, containing all of the necessary elements from Blue- tooth radio antenna to a fully implemented protocol stack. Therefore, the WT12 module provides an ideal solution for developers who want to inte- grate Bluetooth wireless technology into their design with limited knowledge of Bluetooth and RF technologies.

By default, the WT12 module is equipped with powerful and easy-to-use iWRAP firmware. iWRAP enables users to access Bluetooth functionality with simple ACSII commands delivered to the WT12 module over the UART interface.

Besides the iWRAP firmware, the module has an option for other firm- ware options. Standard Host Command Interface (HCI) firmware is supported – an ideal solution for systems where the host system is capable of running the entire Bluetooth stack and profiles, and the WT12 module is utilized as the physical radio over the UART interface.

USB Interface

The device operates as a USB peripheral responding to requests from a master host controller, such as a PC. Both the OHCI and UHCI stan- dards are supported. The set of implemented USB endpoints can behave as specified in the USB section of the Bluetooth v 2.0 and EDR specifica- tion or, alternatively, can appear as a set of endpoints appropriate to USB audio devices, such as speakers.
