Bluetooth®
Audio
Module™
Description
WT32 is the latest generation of Bluegiga’s
Bluetooth
modules. It provides the highest level of integration with
integrated 2.4GHz radio, DSP, battery charger, stereo
codec and antenna ready to hit mono and stereo audio
applications. WT32 is also completely ready to support
the latest
Bluetooth
2.1 standard.
The embedded DSP core allows enhancement of
the product with features, such as, advanced audio
decoding, echo cancellation, noise reduction and data
manipulation.
WT32 combined with Bluegiga’s flexible iWRAP firmware
enables device manufacturers to easily add wireless,
secure and standard based
Bluetooth
connectivity into
new or existing applications with minimal development
and manufacturing effort.
WT32 supports several different integration designs:
The module can
autonomously
be
configured
